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.

I have a bit more time to properly answer this now so here you go:
If (DP)decompression procedures doesn't qualify someone to do gas planning and adhere to pre set ascent rates then Id like to know what the hell it is supposed to do. AN and DP alowes multiple gas decompresion which is about as technical as decompresion gets
Which non GUE course do you think is supposed to prepare you for this?
With reguard to the suitabuility of ratio deco to non trimix dives in the max 50m range.... (bout as far as anyone pushing a nitrox dive should go)
Using deco planner set to 10/100 (simila to ratio deco)
Gas plan for 21/35 and 50% 45 mins at 50m

Ratio deco for 45mins at 50m using 21/35 & 50%
Set point 45m + 5mins add 6mins so deco from 21 and up = 51mins
