I believe I am correct in saying:
This refers to the use of standard gas ranges for back gas and deco and then using the principles of ratio deco for your ascent profiles.
If you look at the PPNitrogen at each gas switch and compare with back gas PPN you will see the picture.
Ratio deco is a little more complicated but as I personally consider it dammed aggressive for general diving except for the unbendable few or young fit divers I wont post the details of how that works. If you use Decoplanner on 30/90GF it will give you the basic shallow profile but you must also consider the GUE deep stops and 5min (or is it 6? I forget) ascent from 6m to the surface.
Personally I used Decoplanner OC with 20/80GFs as I couldn’t give a toss about the extra 10-20mins in the water.
