Do we need to know the diluent type to compute the deco?

So it seems that computing a deco schedule onto which the diver can bail out at any point during the dive is not trivial. Ideally we should give a deco schedule for bailing out at the end of each planned dive segments. So if you have a multilevel dive with three segments, you'd have four schedules: the normal one on CCR and three bailout plans. I think for the moment it'd be good enough to just have a switchbox that says "compute deco on CCR" and if unchecked on OC. > I haven't looked around that hard, but i haven't seen any other planning > software which does a good job of planning bailout of ccr dives.
