What I was trying to say was the ratio deco which most people subscribe to is based around a standard set of gases, standard rates of ascent and standard deco deco gases.
Yes, you can create ratio deco tables for whatever mix and depth you like but I very much doubt that someone who is doing AN & DP will be at that skillset. Indeed the published RD profiles are based on Trimix so it would be out of the scope of this discussion.
However, I cannot see how your 1:1 profile can be more conservative than my 1:1 profile unless you are using a higher ppO2 because 30mins on the bottom equals 30mins of deco.
Can you also tell me the difference between RD and DOTF as I thought they were the same?
Computers wise, I only know of names but don't know capabilities as I just use bottom timers therefore I was just suggesting a variety of options.
