Wow! Run out of air at 100’ and have to breathe off your BC air to make it to the surface.I forget about the breathing from BC thing. I guess it's not something one a should practice for health reasons. But a definite option to get to the surface & survive. Maybe something to consider if OOA at say 100'. I know people have CESAd from that deep. I find the CESA from 30' is easy and I practice it occasionally. Instructors must go up & down a lot, so figuring a way to space out all those student CESAs makes sense. Maybe even do some on Sat. and some on Sun.?
I would think the prudent thing to do would be to train divers extensively (drilled into their heads) to check their air supply and keep their stuff serviced and in good shape. Buddy or no buddy, no excuses!
I wonder if pilots are trained to look at their fuel gauge and keep their planes maintained, or do they just carry a parachute and have to jump every once in a while?
