Yes I run out of gas before I run out of time Latitude. Based on my dive log I get about 44 minutes out of my 100 Cu. Ft. steel and about 37 minutes out of my 80 ct. ft. aluminum on that dive. That’s if I run them totally out and not leave any reserve.

I don’t know if I did the tables right. Computers ruin you since if you don’t use it you lose it. But The way I calculated it using 36% and 32%, I come out 3 pressure groups better if I use the 32% first.

—> 65 feet for 35 min. using 36% puts me in a pressure group of "J" and after an hour interval I’m a pressure group "C". Another 35 min dive to 65 ft with 32% leaves me in a pressure group of S (with a safety stop required)

or if I switch the order of the gas

—> 65 feet for 35 min. using 32% puts me in a pressure group of "M" and after an hour interval I’m a pressure group "D". Another dive to 65 feet for 35 min. leaves me in a pressure group "P" (no safety stop required)

Again, that’s if I did the tables right, Haven’t actually manually done tables in awhile. It might also make a difference since I have to round 65 feet up to 70 on the 32% RDP since it doesn’t have a 65 foot column like the 36% dive planner does. I guess I would get a more accurate comparison if I just manually did both dives to 70 feet since both RDPs have a 70 ft column.
