The ONE field with no MultiDeco counterpart is Dive Kit's airBreakPO2Threshold, 1.4 bar: Dive Kit starts the 20-minute clock whenever the gas being breathed is at or above that ppO2 at the stop depth, so EANx50 at 21 m and 18 m also counts toward a break, while MultiDeco times the oxygen stop itself. On this profile the difference is invisible, because the EANx50 run is only 6 minutes long and the clock resets at 15 m where EANx50 falls to 1.25 bar, so both tools start counting at the first oxygen minute.
