Optimal Pony Bottle Size for Failure at 100ft?

The only thing I wouldn't do is spend 2-3 minutes composing myself. Once there's an emergency we abort asap.

Winner! Winner! Give the man a pollo dinner!

It is a programmed action ... If "X" happens, then next heartbeat sees plan "Y" enacted - transitioned to alt gas source and moving to the surface at 60 FPS, filed direct, course approved, contact arrival ...,ETA two minutes and ten seconds, assuming a rec dive, not the "WTF & I wonder what went wrong & maybe I should try figuring out what to do about it" plan.

I go by the US navy dive manual. The formula is a little different we use 1.4 acfm but you are coving a lot. The only thing I wouldn't do is spend 2-3 minutes composing myself. Once there's an emergency we abort asap.

Ever watch Miracle on the Hudson? Not taking any time to think of your problem before acting and just immediately heading up is wildly optimistic.

Aviate, Navigate, Communicate. Troubleshooting is a consistent, but subordinate task to the 3 primary ones.

Isolate-to/switch-to/get-to to a stable air source, ascend, whoops!

The SCUBA twist is the ethical burden of making a reasonable attempt to inform a buddy of the situation before disappearing to the surface. Which reorders things a bit to: Air source, communicaton (if possible), surface.
Troubleshooting is subordinate to buddy responsibility and also to forcing your survival to be in your buddys hands.o

Solo: if it isnt't obvious, and obviously fixable, get thee to the surface.

Allowing gas for 2-3 minutes to get to the anchor line or to into the wreck, shoot a DSMB and ascend is solid planning.

And if go OOG at 100fsw on an 80 or anything bigger, you’re likely over the NDL. Bolt to the surface without thought might not be the best immediate action.
