Good enough, Ken. A dive like Farnsworth, Ship Rock, Ruby E, Yukon, etc, I always use rule of thirds. So that puts me on the upline with 800psi, no ifs ands or butts. I can say that I've seen an OOA one time in my life and that was a new diver who said after the rescue,
"Well, I use this tank in the pool all the time and it lasts all day"
This was a dive to 80ft and after a long lecture about gas density and ambient pressure, I doubt seriously if she ever made the same mistake again.
