This thread is very similar to quite a few others ones that I have stumbled across in the archives here on ScubaBoard. For good reading, just enter "SAC formula" in the search box at the top of the page. This SAC/RMV, gas management topic always seems to get a lot of banter going back and forth.

A few months ago I was reading some of the other SAC/RMV threads and they sucessfully got me throughly confused after reading all of the back and forth about SAC, RMV and probably a half a dozen other issues concerning gas management. Luckily Bob's article really cleared up a lot of stuff for me.
