Inspiration Cave Dive

[DRE]

Chuck,

excuse my ignorance but don't you still have to plan the dive in terms of available gas to be able to exit the cave on OC from furthest penetration, ie absolute worse case scenario? Or do you plan the dive around the idea that if the entire team is on CC (let's say three divers - the ideal cave team), the possibility of all three divers having to bail out to OC is so remote that you can use lesser gas requirements? If the latter holds true, how do you calculate your contingencies, ie one or two divers having to bailout to OC, having to bailout to SCR mode or flying the unit manually, etc.
