Thus, GFs and conservatism settings. It is not hard to tune your computer to match your body. Even untuned, millions of dives are made annually without any issue. I trust the computer more than the diver.Which is my point, they are averages, safe for most but to assume one person diving an algorithm has the same physical response is silly, some people get bent and some (most) don’t with the exact same dive, the computer just runs the program.
