Nice figures, but I like the ones on women better.
I was surprised you said that regs won't generally work below 300 psi. I think mine are lower tech, because I can suck a tank dry... annoys the dive shops. Also I suspect that older regs give better warning of OOA. I mean that's just how we did it before SPG's.
I have never once in 34 years of diving run out of air accidently. Intentionally is another story.
As I remember, I just relaxed (no 15 minute, but I am trained to relax my breathing) I think I went 7 minutes on the 6 cu ft tank. It amazed me. I expected about 3 minutes max. The tank was not empty, but I stopped cuz I was sick of waiting for it to empty.
A simple question. What is a typical air usage (cubic feet/minute) on the surface. ... maybe for a little guy like me.
Enjoy, seahunt
