첫 정지가 30 m 대 33 m입니다. 감압이 조금 더 얕은 곳에 놓이고 수면까지 3분 더 걸립니다.

MultiDeco는 33 m와 30 m에서 각각 1분씩 머뭅니다. Dive Kit은 33 m 정지를 그대로 지나가고 30 m에서 머물기 시작해, 그보다 얕은 정지에서 더 오래 머뭅니다. 총 수면 도달 시간은 근접하고(48 대 45 min), 기체 전환은 정확히 일치합니다(EAN50 21 m, O₂ 6 m). 헬륨 다이빙에서 나타나는 정지 분포 효과입니다(general/stopDistribution 참조).

Two differences on this deep 55%-helium dive: first stop 39 m vs 48 m (the same deco placed shallower), and CNS 84% vs 65% (our more cautious oxygen method).

The stops: MultiDeco lists deep stops from 48 m down. Dive Kit climbs through the deepest of them and starts holding at 39 m, because on a 55%-helium dive the fast tissues breathe off so fast that the ceiling drops faster than you climb. The total decompression is close (72 min of stops against MultiDeco's 76) and the time to surface is within 4 minutes (85 vs 81 min); the deco is just placed shallower (see general/stopDistribution). The CNS: Dive Kit reads 84% against MultiDeco's 65%. This is the one difference that looks large, and it is deliberate. At the 6 m oxygen stop the oxygen pressure sits in a steep part of the NOAA toxicity curve, and Dive Kit uses the more cautious ambient-pressure method, so its oxygen clock ticks faster there (see general/cnsBasis). All three gas switches match MultiDeco: Tx21/35 at 57 m, EAN50 at 21 m, oxygen at 6 m. Tx21/35 used to switch one stop shallower, at 54 m; since ENGINE_VERSION 18 a gas may sit up to 0.03 bar over its cap, which reaches the 57 m stop MultiDeco uses, and the extra 3 m on the richer gas also adds to the CNS.

Same dive as S2 with looser GF. First stop shallower (15 vs 18 m), identical decozone (32.3 m).

This shows the gradient-factor setting working as expected: GF 50/80 gives a shallower first stop and a shorter schedule than S2's 30/70 (52 vs 74 min to surface), while the decozone start stays at 32.3 m because it does not depend on your gradient factors. CNS and OTU match (12 vs 12%, 32 vs 32). See general/decozoneStart.

First stop 24 m vs 27 m, on a helium dive in fresh water. Same total deco, placed shallower.

MultiDeco lists a stop at 27 m that lasts only 8 seconds. Dive Kit climbs through it, because the fast helium tissues breathe off during the climb and the ceiling has already dropped below that depth, so its first real hold is 24 m and it holds longer below. The total time to surface is close (43 vs 42 min) and the EAN50 switch matches at 21 m. This is the stop-distribution effect (see general/stopDistribution).

Multi-level dive. Time to surface one minute over MultiDeco; first stop one step apart.

With both tools running the same at-depth profile (45 m for about 8 min, then 30 m for 15 min; MultiDeco folds the 2 min descent into the entered first-level time), the time to surface (23 vs 22 min), CNS (14 vs 13%) and the EAN50 switch (21 m) all land close. Decozone is within 1 m (21.3 vs 22 m). The first listed stop is 12 m vs MultiDeco's 15 m, one 3 m step, the stop-distribution effect (small here, with little fast gas). Gas density shows the usual temperature offset. The time to surface was 23 min before 2.10.0: ENG-4 hangs the gradient-factor line from the deepest ceiling of the bottom phase rather than re-reading it after the shallower 30 m level, which moved this plan 1 minute onto MultiDeco's answer (22 min). ENGINE_VERSION 18 moves it back to 23: salt water now converts at its physical 9.95 m per bar, a little more pressure at every depth, and the 3 m stop grows by a minute. See general/stopDistribution and general/gasDensity.

Deep trimix. Every deco-gas switch matches MultiDeco; time to surface within a minute.

The first switch, to Tx35/25, is at 33 m in both tools. That gas sits right at its oxygen cap around 33 m; until ENGINE_VERSION 18 Dive Kit stayed just under the cap and switched a stop shallower, at 30 m, and it now accepts a gas up to 0.03 bar over its cap, the same stop MultiDeco picks. The EAN50 and oxygen switches match exactly, at 21 m and 6 m. Dive Kit's first stop is 30 m against MultiDeco's 39 m, the usual stop-distribution effect on a dive with helium (see general/stopDistribution). Total time to surface is within a minute (55 vs 56). CNS reads 8 points higher (60 vs 52%), from our more cautious oxygen method (see general/cnsBasis).

Low GF (20/75). Close match, and the decozone confirms it does not move with your gradient factors.

At GF 20/75 the decozone is 37 m (Dive Kit 37.3 vs MultiDeco 37), the same depth this dive would show at any GF, which confirms the decozone does not move with your gradient factors while the first stop does. CNS (25 vs 24%), OTU (66 vs 64) and the EAN50 switch (21 m) match closely, and time to surface is 46 vs 43 min: salt water now converts at its physical 9.95 m per bar, and the extra pressure adds two minutes of shallow stops; the rest is Dive Kit rounding time to surface up to the next whole minute, as the app shows it. Dive Kit's first stop is 27 m vs MultiDeco's 30 m (MultiDeco lists a stop of well under a minute at 30 m that Dive Kit climbs through; see general/stopDistribution). See also general/decozoneStart.

6 m last stop. The deep stops match; Dive Kit holds the 6 m stop 3 minutes less (58 vs 61), and runs 2 min longer to the surface in total.

Both tools run the deep stops the same way and reach 6 m equally loaded. The only real difference is the 6 m hold: Dive Kit holds 58 minutes, MultiDeco 61. Dive Kit leaves as soon as you can surface within your GF-High setting; MultiDeco holds a little longer. Total time to surface is 82 vs 80 min: since ENGINE_VERSION 18 salt water converts at its physical 9.95 m per bar, which adds a minute at 9 m and one at 6 m and outweighs the shorter 6 m hold; Dive Kit's figure is rounded up to the next whole minute, as the app shows it. The first stop (21 m), decozone (31.8 vs 32 m) and CNS (11 vs 11%) all match. On the 6 m hold alone this is still the one kind of dive where MultiDeco is the more conservative of the two (see general/stopDistribution).

Altitude (2025 m) with a 6 m last stop. Same pattern as A4, a bit larger: Dive Kit holds the 6 m stop 7 minutes less (33 vs 40).

Like A4, both tools match down to 6 m, then Dive Kit leaves the 6 m stop sooner (33 minutes vs 40) once you can surface within your GF-High setting. Total time to surface is 46 vs 48 min. The gap is bigger than at sea level. Part of that is altitude stretching the final hold for both tools, and part may be a small difference in how each tool handles altitude pressure. The decozone matches (21.1 vs 22 m) and the first stop is one 3 m step apart (12 vs 15 m). See general/stopDistribution.

Deep air. The gas-density hazard and the gas switch both check out.

Decozone (39 vs 38 m), CNS (24 vs 23%) and the EAN50 switch (21 m) match. First stop 24 vs 27 m, one step, the stop-distribution effect (small on air, with no fast helium to drive it). The point of this dive shows clearly: gas density at 55 m on air is 8 g/L in Dive Kit and 7.7 in MultiDeco, both far above the 6.2 g/L danger line (the 4% gap is mostly the water-temperature offset), and Dive Kit also raises a narcosis (END) warning. See general/gasDensity.

Repetitive dive. Leftover nitrogen carries across correctly; OTU is added up across both dives.

Dive 2, after a 60-minute surface interval, is much heavier than the same dive done fresh, which confirms the leftover nitrogen carries across: its 6 m stop runs 49 min and its time to surface 61 min, against MultiDeco's 53 and 61 for the same dive (in MultiDeco's own capture, dive 1 held 22 min at 6 m). The first stop (12 m, exact), decozone (20.7 vs 21 m) and CNS (10 vs 10%) match. Both tools carry CNS across the surface interval and let it decay. The one figure that differs by design is OTU: Dive Kit adds it up across both dives (36, about 18 from dive 1 plus 18 from dive 2), which reads OTU as a daily dose, while MultiDeco shows it per dive (18). See general/stopDistribution.

ppO2 band boundary at 45% O2: EAN45 switches at 24 m in both tools, confirming the >=45% -> rich (1.6) convention.

EAN45 sits exactly on the mid/rich band edge (45% O2). Dive Kit caps a gas at 1.6 bar once its O2 is >= 45% (rich), so EAN45's MOD is ~25.3 m and it switches at the 24 m stop; if it were treated as mid (1.5) it would wait until 21 m. MultiDeco switches EAN45 at 24 m with a PPO₂ of 1.52, letting the gas run above 1.5, so it also caps at 1.6, meaning the >= boundary is inclusive-to-rich in both tools. O2 switches at 6 m exactly. (Dive Kit lists the 24 m point as a gas-switch stage and its first deco stop as 21 m, while MultiDeco lists 24 m as the first stop, but both switch EAN45 at 24 m.) CNS reads a few points higher in Dive Kit (39 vs 34%, the ambient-ppO2 method) and gas density carries the usual temperature offset.

Precise (1-second) stop times cross-checked against MultiDeco at min stop = 1 s. Sub-minute stops track closely; switches and TTS agree once the gas-switch-time accounting is allowed for.

One of three scenarios run in PRECISE mode (Dive Kit stopRoundingSeconds=0, MultiDeco min stop = 1 s), alongside G1 and G2, so it cross-checks Dive Kit's second-resolution output directly. It also exercises a travel-gas descent (descend on Tx35/25, switch to Tx18/45 at 30 m) and a multi-level profile (60 m then 42 m). The sub-minute stops align within about 40 s at each depth and MultiDeco starts holding at 27 m and Dive Kit at 24 m, one 3 m step apart; the EAN50 (21 m) and O2 (6 m) switches match exactly. Tx35/25 is two stops apart, 33 m against 27: since ENGINE_VERSION 18 Dive Kit lets a gas sit up to 0.03 bar over its cap, which moved this switch from 30 to 33 m. Three documented differences, none of them engine errors: (1) Dive Kit adds an explicit ~1-min gas-switch hold at each of the three switches, which MultiDeco folds into the adjacent stop, so Dive Kit's time to surface runs longer (58 vs 54 min; strip those 3 min and it is within about 1 min); (2) CNS reads higher in Dive Kit (69 vs 54%, the ambient-ppO2 method, see general/cnsBasis), pronounced here because of the long 1.6-bar O2 stop; (3) decozone start differs (Dive Kit 35 m vs MultiDeco 45 m) because Dive Kit computes it from the end-of-bottom tissue state, after the 42 m level off-gasses the fast tissues, whereas on a single-level dive the two coincide. The operational first stop is one 3 m step apart. See general/gasSwitchCap, general/cnsBasis, general/decozoneStart. Since 2.10.0 the first stop reads 24 m rather than 27 m and the unrounded time to surface 57.6 rather than 58.9 minutes: ENG-4 hangs the gradient-factor line from the deepest ceiling of the bottom phase instead of re-reading it after the shallower 42 m level, which is a gentler line and one step shallower on the first hold. Total runtime moved 1 minute closer to MultiDeco's. ENGINE_VERSION 18 then adds 0.3 min (57.6 to 57.9): salt water at its physical 9.95 m per bar, partly offset by the deeper Tx35/25 switch.

GF-high sensitivity baseline (50/80): precise-mode air dive with a 6 m last stop. Pairs with G2 to publish how much the surfacing gradient moves the shallow hold.

Half of the GF-high pair born from the June 2026 unsurfaceable-stop investigation. Same dive as G2 with GF 50/80. Dive Kit holds 15/12/9/6 and MultiDeco lists the same set plus a one-second touch at 18 m, and both agree on the 6 m hold dominating the schedule (37.3 min in Dive Kit, 38.4 in MultiDeco). Entered-time convention: 22:00 typed into both tools, descent folded in (Lvl 19:45 at depth), in Dive Kit via 'Include travel in level time' = ON, the first cross-reference scenarios to exercise that setting end-to-end including the share URL.

차이가 나는 이유

GF-high sensitivity extreme (50/50): the 6 m hold stretches to ~3 hours in both tools. The base plan completes; with more loading it would tip into 'deco cannot complete'.

At GF high 50 on air with a 6 m last stop, tissues at the stop converge toward ~1.23 bar inspired pN2, above what a 50% surfacing gradient tolerates for the mid compartments, so the hold balloons (Dive Kit 165.6 min at 6 m, MultiDeco 174:35) and only barely clears. Time to surface runs 188 vs 196 min. Add ~5 more minutes of bottom time and the stop never clears at all: that configuration is what drove Dive Kit's stop-never-clears detection and GF-high auto-raise (engine warning 18). The published pair documents the cliff edge from the completable side.

The plan as the diver typed it. Neither planner weaves, because nothing is owed above 21 m, and the two first stops are one 3 m step apart. Dive Kit takes its 35/38 higher up the ascent than MultiDeco does.

A 21 m level on the back of a 75 m trimix dive that runs 5 minutes at depth. The ceiling at the end of the deep leg still sits below 21 m, so there is nothing to weave in front of the level and both planners ascend to it in one leg. Dive Kit holds its first stop at 9 m and MultiDeco at 12 m, one 3 m step, the usual stop-distribution effect on a helium dive (see general/stopDistribution). Time to surface from the end of the level is 20 against 19 minutes and total runtime 44 against 42. Decompression is 14 minutes against 16. The one real behavioural difference is where the 35/38 is taken up. Dive Kit switches at 33 m, the deepest stop where that mix is within 0.03 bar of its ppO2 cap (30 m before ENGINE_VERSION 18), and MultiDeco switches at 21 m on arrival at the level. Dive Kit therefore breathes 696 litres of 35/38 against MultiDeco's 512, and 1791 litres of 17/60 against 1932. That earlier, richer gas is also most of the CNS gap: 51 % against 36 %, on top of the ambient-ppO2 method Dive Kit uses throughout (see general/cnsBasis). OTU lands at 61 against 59. Decozone start reads 18.6 m against MultiDeco's 50 m. That is the multi-level definition difference, not a model gap: Dive Kit computes it from the tissue state at the end of the bottom phase, which here is the end of the 21 m level, while MultiDeco reports the deepest-point figure (see general/decozoneStart). Level times are the at-depth values MultiDeco itself resolved, because it does not treat every level the same way: the time typed for the first level, or for a level deeper than the one before it, includes the travel to reach it, while the time typed for a shallower later level is already the time at depth. Both planners therefore run the same profile. Behaviour class: flies through, with nothing to weave.

Both planners weave. They start holding at the same 36 m, and they disagree about which gas the woven stops are breathed on, which is most of the CNS and runtime gap.

The same profile on a 25-minute bottom, where the ceiling at the end of the deep leg is far below the 21 m the diver asked for. Both planners insert the owed stops in front of the level and both start at 36 m, the strongest agreement in the series on the feature this scenario exists to test. They then hold at the same five depths, 36 m down to 24 m, before the level. What differs is the gas. MultiDeco stays on the 17/60 bottom mix through every woven stop and takes the 35/38 only on arrival at the level. Dive Kit switches at 33 m, the deepest stop where the 35/38 is within 0.03 bar of its ppO2 cap (30 m before ENGINE_VERSION 18), so its 33, 30, 27 and 24 m stops are breathed on the richer mix at 1.52, 1.41, 1.30 and 1.2 bar. That buys shorter woven stops, 8 minutes against MultiDeco's 14.67, and it costs oxygen exposure: CNS 182 % against 132 %, of which the ambient-ppO2 method accounts for a few points and the earlier switch for the rest (see general/cnsBasis and general/gasSwitchCap). OTU is almost identical, 203 against 205. Downstream the two schedules converge. Dive Kit owes 80 minutes of decompression against MultiDeco's 96, time to surface 78 against 84 minutes, and total runtime 130 against 140. The last stop is the bulk of it either way, 44 minutes at 6 m against 49. Decozone start reads 24.4 m against 58 m, the same multi-level definition difference as W1 (see general/decozoneStart). Level times are the at-depth values MultiDeco itself resolved, because it does not treat every level the same way: the time typed for the first level, or for a level deeper than the one before it, includes the travel to reach it, while the time typed for a shallower later level is already the time at depth. Both planners therefore run the same profile. Behaviour class: weaves, in both planners.

Two levels above the ceiling in a row. Both planners weave in front of the 15 m level and neither weaves in front of the 30 m one, and the runtimes land on the same minute.

A 60 m trimix dive with levels at 30 m and 15 m. The leg from 60 m to the 30 m level is clear of the ceiling in both planners, so nothing is woven there. The leg from 30 m to 15 m is not: MultiDeco inserts two stops, 21 m for 0:40 and 18 m for 3 minutes, and Dive Kit inserts one, 18 m for a minute. First stop is 18 m against 21 m, one 3 m step. As in W1 and W2, Dive Kit takes the richer mix earlier: it switches to the EANx50 at 21 m, its ppO2 cap depth, and breathes the woven 18 m stop on it, while MultiDeco holds the 21/35 through both woven stops and picks the EANx50 up on arrival at the 15 m level. Dive Kit draws 759 litres of EANx50 against 531. CNS is 55 % against 44 % and OTU 97 against 95. The totals are close. Decompression 31 minutes against 36, time to surface 34 minutes in both, total runtime 76 in both. The second woven leg starting from the state the first one left behind is the point of this scenario, and the gradient-factor line stays hung from the deepest ceiling of the bottom phase rather than re-anchoring on each leg (ENG-4). Decozone start reads 17.4 m against 45 m, the multi-level definition difference (see general/decozoneStart). Level times are the at-depth values MultiDeco itself resolved, because it does not treat every level the same way: the time typed for the first level, or for a level deeper than the one before it, includes the travel to reach it, while the time typed for a shallower later level is already the time at depth. Both planners therefore run the same profile. Behaviour class: weaves, in both planners.

A yo-yo. Both planners fly straight to the 21 m level, then go back down to 40 m. Dive Kit swaps off the EANx50 before the descent; MultiDeco carries it down to 40 m, where it sits near 2.5 bar of oxygen, and that is the whole CNS story.

50 m, up to a 21 m level on EANx50, then back down to 40 m on the 21/35 before the final ascent. Nothing is owed above 21 m, so both planners reach the level with an ordinary ascent and neither weaves. The interesting half is the descent that follows. Dive Kit changes gas at the departure depth: it switches to the 21/35 at 21 m and then descends, because the deeper level's gas is the leaner one and there is no later moment at which it could safely be taken up (see general/levelsAndCeiling). MultiDeco descends on the EANx50 it took up at the level and swaps to the 21/35 only on arrival at 40 m. EANx50 at 40 m is about 2.5 bar of oxygen, well past any published working limit, and MultiDeco's own CNS reflects it: 96 % against Dive Kit's 42 %. OTU lands at 77 in both, which shows the gap is the short, very rich descent leg rather than the dive as a whole. Dive Kit raises no warning here because it never breathes the mix that deep. The schedules themselves are close: first stop 9 m against 12 m, decompression 17 minutes against 18.67, time to surface 25 against 23 minutes, total runtime 59 against 56. This is also the one W scenario where decozone start agrees, 25.8 m against 25 m, because the dive's last level is its deep one and the two definitions coincide (see general/decozoneStart). Level times are the at-depth values MultiDeco itself resolved, because it does not treat every level the same way: the time typed for the first level, or for a level deeper than the one before it, includes the travel to reach it, while the time typed for a shallower later level is already the time at depth. Both planners therefore run the same profile. Behaviour class: flies through, then re-descends because the diver asked it to.

The ascent-gas rule with a 6 m oxygen level. Both planners weave, both take the oxygen only on arrival at 6 m, and Dive Kit starts holding one step deeper.

40 m on air for 20 minutes, then a 6 m level on oxygen. Both planners insert the owed stops in front of the level and both breathe them on air: MultiDeco holds at 12 m for 2.88 minutes and 9 m for 3, Dive Kit at 15 m for 2, 12 m for 3 and 9 m for 3. First stop 15 m against 12 m, one 3 m step deeper. Neither planner moves the diver onto the oxygen during the ascent, which is the question this scenario was built to answer: both switch at 6 m, on arrival. Dive Kit carries 9 minutes of decompression against MultiDeco's 6.21 and finishes with a minute at 3 m where MultiDeco holds 0:20, so time to surface from the end of the level is 3 against 2 minutes and total runtime 45 against 40. CNS reads 31 % against 22 % and OTU 42 against 40; the oxygen at 6 m is 1.62 bar in Dive Kit and 1.6 in MultiDeco, and the gap is the ambient-ppO2 method plus the longer hold (see general/cnsBasis). Decozone start reads 7 m against 28 m, the multi-level definition difference in its sharpest form, because this dive's last level is its shallowest (see general/decozoneStart). Level times are the at-depth values MultiDeco itself resolved, because it does not treat every level the same way: the time typed for the first level, or for a level deeper than the one before it, includes the travel to reach it, while the time typed for a shallower later level is already the time at depth. Both planners therefore run the same profile. Behaviour class: weaves, in both planners.

A woven leg on the rebreather loop, and the closest match in the series. Both planners weave the same two stops in front of the 21 m level, hold the same times at 15, 12, 9 and 6 m, and read the same time to surface, with runtimes a minute apart. The Full Bailout plans now leave the loop onto the same gas and also read the same time to surface, a minute apart on runtime. Baltic is captured here too, the only scenario in the set with three planners on it: it weaves as well, one stop deeper, and its bailout leaves the loop onto the same richest usable gas.

60 m for 25 minutes on the loop at setpoint 1.3 with a 10/50 diluent, then a 21 m loop level. The ceiling at the end of the deep leg sits below 21 m, so both planners insert the owed stops in front of the level and hold them on the loop: 27 m and 24 m, breathed at 1.3 on the 10/50 rather than on a deco setpoint. First stop is 27 m in both. The loop schedules then track each other almost stop for stop. MultiDeco holds 3, 5 and 7 minutes at 15, 12 and 9 m, Dive Kit holds exactly the same three, and both hold 11 at 6 m. The only stop that parts is the last: 17 minutes against 18 at 3 m. Decompression is 45 minutes against MultiDeco's 46.33, time to surface from the end of the level 46 minutes in both, and total runtime 87 in Dive Kit against 86 in MultiDeco. Dive Kit's run time is 86 minutes 20 seconds, and Dive Kit shows run time rounded up to the next whole minute, as the app does, so it reads 87. CNS reads 48 % against 47 % and OTU 127 against 123. Decozone start reads 23.2 m against 44 m, the multi-level definition difference the rest of the series shows (see general/decozoneStart). The Full Bailout plan leaves the loop at the end of the 21 m level in both tools, and both leave it onto the EANx50 with one switch. Dive Kit picks the richest gas on the diver's rack that is breathable at the bail depth, which at 21 m is the EANx50 at 1.56 bar: the 21/35 reads 0.66 and the 10/50 the loop breathes as diluent reads 0.31, and oxygen is out of its depth. The racks are still not the same, because MultiDeco was given three bailout mixes (21/35, EANx50 and oxygen) while Dive Kit offers every cylinder on the plan and so counts the 10/50 as well, but that no longer changes the answer: the extra cylinder is not the richest usable mix, so it is not chosen, and cylinder order cannot reach the schedule at all. Both then switch onto oxygen at 6 m, and both put the first stop at 27 m. Dive Kit used to take the first cylinder in the diver's list whose maximum operating depth reached the bail depth, which here was the 10/50, and bill three one-minute switches at 21 m walking up the rack to the EANx50 it should have started on. The times to surface now match. MultiDeco's bailout runs 43 minutes to surface for a runtime of 83, against its own loop plan's 86. Dive Kit's also runs 43 to surface, for a runtime of 84 (rounded up from 83 and a fraction) against its own loop plan's 87, so the bailout reads shorter than the loop in both tools, which is the direction a bailout onto rich open circuit should read. Decompression is 38 minutes against MultiDeco's 41. Stop for stop the schedules are within a minute at every depth: 2 against 2 at 15 m, 4 against 5 at 12 m, 7 against 7 at 9 m, 9 against 10 at 6 m and 16 against 17 at 3 m. The oxygen clocks agree on direction in both tools: bailout CNS is higher than loop CNS (MultiDeco 55 % against 47 %, Dive Kit 65 % against 48 %) while bailout OTU is lower than loop OTU (MultiDeco 117 against 123, Dive Kit 121 against 127). Dive Kit draws 534 litres of EANx50 and 575 of oxygen, and 0 litres from each of the 10/50 and the 21/35, which it never breathes; MultiDeco reports 680 and 580 for the two mixes it tracks. Baltic is captured on W6 as well, loop and bailout, which makes this the one scenario in the set with three planners on it. Baltic weaves too, and one stop deeper. It holds 0:40 at 30 m, then 1 minute at 27 m and 1 minute at 24 m before the 21 m level, against MultiDeco's 0:20 at 27 m and 2 minutes at 24 m, and Dive Kit's 1 minute at 27 m and 1 minute at 24 m. Its first stop is therefore 30 m where both the others read 27 m. After the level the three converge. Baltic holds 2, 4, 7, 11 and 18 minutes at 15, 12, 9, 6 and 3 m, with an extra 0:40 at 18 m neither other planner lists, and it surfaces at runtime 86, the same minute MultiDeco reads and one under Dive Kit's rounded-up 87. Time to surface measured from the end of the 21 m level is 44 minutes in Baltic and 46 in both MultiDeco and Dive Kit. CNS sits within a point across the three: 48 % in Baltic, 47 % in MultiDeco and 48 % in Dive Kit. OTU reads 127, 123 and 127. Baltic's own DecoTime figure reads 52 because it counts decompression from the moment the ascent out of the 60 m level begins, so the woven stops and the ascent to the 21 m level are inside it; it is not the same quantity as Dive Kit's 45. Baltic's decozone marker reads 45 m against MultiDeco's 44, both of them the deepest-point definition Dive Kit does not use (see general/decozoneStart). Baltic's Full Bailout leaves the loop at the end of the 21 m level, the same point the other two bail from, and it leaves onto the same gas. It takes the EANx50 at 21 m at 1.55 bar, passing over both the 21/35 and the 10/50 diluent already in the loop, then oxygen at 6 m at 1.60 bar. All three planners answer the bailout-gas question the same way. Where Baltic parts from the other two is what the bailout costs it. Its bailout runs to runtime 86, exactly its own loop runtime, where MultiDeco's runs 83 against its loop's 86 and Dive Kit's 84 against its loop's 87, each three minutes shorter than the loop it branches off. Time to surface from the end of the level is 44 minutes in Baltic against 43 in both MultiDeco and Dive Kit. Stop for stop the three sit within two minutes everywhere: Baltic holds 0:40 at 18 m, a stop neither other planner lists, then 1, 3, 8, 9 and 18 minutes at 15, 12, 9, 6 and 3 m, against MultiDeco's 2, 5, 7, 10 and 17 and Dive Kit's 2, 4, 7, 9 and 16. Baltic reads CNS 64 % and OTU 127 for the bailout, so its bailout CNS sits above its loop CNS of 48 % the way both others do; its bailout OTU is the one figure that does not follow, reading the same 127 as its loop where MultiDeco and Dive Kit both drop. It draws 594.8 litres of EANx50 and 608.3 of oxygen, on top of 27.9 litres of loop oxygen spent before the bail. Its DecoTime for the run reads 51, its own from-the-start-of-the-ascent figure again, and its decozone marker recomputes to 20 m from the bail point where the loop run's read 45 m. One figure needs reading with care rather than comparing: Baltic reports the first stop of this run as 18 m, the first one after the bail, where the MultiDeco and Dive Kit columns report 27 m, the first stop in the end-to-end schedule including the woven loop stops the run shares with the loop plan. Baltic also offers a bailout from the end of the 60 m level, and that run is the plainest statement of the gas rule anywhere in the set. Bailing at 60 m it leaves the loop onto the 21/35 at 1.47 bar, the richest mix on the rack breathable that deep, skipping the 10/50 diluent already in the loop, and then picks up the EANx50 at 21 m and the oxygen at 6 m exactly as the 21 m run does. Richest usable gas at the depth you bail from, in a fourth independent planner, tested at two different depths on one rack. That run is pasted in the capture sheet and is not encoded here, because a bailout from the bottom is not a column the other two publish. Level times are the at-depth values MultiDeco itself resolved, because it does not treat every level the same way: the time typed for the first level, or for a level deeper than the one before it, includes the travel to reach it, while the time typed for a shallower later level is already the time at depth. Both planners therefore run the same profile. Behaviour class: weaves, in all three planners.

차이가 나는 이유

The control, and it lands within two minutes. Same three stop depths, same first stop, and a runtime of 61 minutes against MultiDeco's 59.

30 m then 20 m on air, a multi-level dive whose shallower level sits well below the ceiling, so nothing is woven and nothing may move. Both planners hold at 9 m, 6 m and 3 m, both start at 9 m, and total runtime is 61 minutes against 59. Decompression is 19 minutes against MultiDeco's 17.67, distributed differently across the three stops in the usual way: Dive Kit 4 / 7 / 8 minutes against MultiDeco's 0:40 / 5 / 12 (see general/stopDistribution). Time to surface from the end of the level is 22 against 20 minutes, CNS 8 % in both and OTU 23 in both. The two minutes over have two sources, and neither is the anchor. One is ENGINE_VERSION 18: salt water now converts at its physical 9.95 m per bar, a little more pressure at every depth, and the 6 m stop grows from 6 to 7 minutes. The other is display: Dive Kit's run time lands at 60 minutes 30 seconds, and Dive Kit shows run time rounded up to the next whole minute, as the app does, so it reads 61. That agreement is the point. Plans of this shape carried more decompression through 2.9.x, before ENG-4 hung the gradient-factor line from the deepest ceiling of the bottom phase instead of re-reading it once the 20 m level had off-gassed the diver. On this control the ENG-4 anchor put Dive Kit's runtime on MultiDeco's 59 minutes at ENGINE_VERSION 17. It also proves no woven branch touches a plan that does not need one: if a stage here ever carried a level index, the weave would have leaked. Decozone start reads 15.2 m against 21 m, the same multi-level definition difference as the rest of the series (see general/decozoneStart). Level times are the at-depth values MultiDeco itself resolved, because it does not treat every level the same way: the time typed for the first level, or for a level deeper than the one before it, includes the travel to reach it, while the time typed for a shallower later level is already the time at depth. Both planners therefore run the same profile. Behaviour class: nothing to weave, which is the point of a control.
