do I understand you correctly that with multiple sensors, we would give up to try to determine which gas the diver is breathing (at a given time)? In the old model, we did (and yes, that could be wrong when we were missing gas changes that were actually happening). But as Rick said, we need that information to determine not only the TankItem but also the tissue levels (which have consequences for the ceilings and the TTS as well as the partial pressure graphs). So, I think it would not be wise to throw that information out of the window.

Best
Robert
