Do we need to know the diluent type to compute the deco? I'm only
trained for air so I hadn't thought of that...

A worst point does not necessarily exist: early in the dive,
compartments with short half times will be the bottleneck, so a bailout
plan would give short but deep stops; later in the dive it will be
compartments with longer half times, and you will have longer but
shallower stops. 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.

Most people I know use V-Planner.

Cheers.
