Is there a way to make a reasonable prediction on how a conservation setting on my DSAT computer compare to a PZ+ algorithm? I have two Aeris Atmos AI computers which run DSAT. The nitrogen bar has eight blocks of which five are black, two are yellow and one is red. I can setup the nitrogen bar graph to increase/decrease the conservative factor of the computer's algorithm, but do not know how much of an increase or decrease in conservatism I should expect for each change in the bar graph blocks. Understanding the red zone borders on, or may initiate a requirement for deco, which I do not plan to do, or have ever needed to use, I have been using the first yellow block as a reasonable conservative setting. However, I do not know where that first yellow block might compare to a computer running PZ+ at its most liberal setting. Having some idea of the differences might be helpful if I am diving with a buddy using a PZ+ computer. At my age, I do not want to use the most liberal setting available on my computer, but I also don't want to use a setting that is overly conservative for the type of rec diving I do, usually above 100', warm water, single tank AL80, and a max of 3-4 dives a day for no more than 5 consecutive days.
