I find great enjoyment poking along looking at stuff sometimes taking side excursions but not covering lots of distance. You need to know your bailout range and the penetration distance can be planned before hand so I know how far I can go on my bailout regardless of time.
of course. but in an overhead you have to assume an exit swim speed to make sure you have enough bail gas for your given exit distance.

The other factors 1/3 O2, 1/3 dil are time based
O2 and especially dil is very much cave profile as well as time/metabolism based.

but bailout gas is basically static until it gets used. Now I have no experience exploring new caves so then all bets are off but for well mapped and planned dives I know my bailout turn point before I start the dive.
as does any good ccr diver
