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?

Not much, just DOTF is generaly accepted as being the GUE version using the GUE standard gas list. Ratio deco can be calculated on pret much any gas list

My 1:1 profile will be based on max depth and run time will be from leaving the surface to starting my ascent.

I beleive yours is average depth starting your time from the bottom of the shot.

QED I will be doing more deco than you dispite leaving the bottom at the same time.

But i am old and fat and you are young (ger) and fit

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.

Thats what i thaught.

From what I have seen the only cheep alternative two gas computer to the VR3 is the VR2.

If there is a cheeper better computer id like to know what it is.

Unless the Vytec DS and the Marres have started giving out proper TTS info they are still crap.
