I remember hearing or reading somewhere (but can't find it now) on how much to cut down time for deco stops at or above 20' that are planned on air but using 100% O2 instead.
For instance, if using Deco air tables but plan on using 100% at 20' or above, how do you adjust the times for those stops?
Or if using V-Planner in evaluation mode which does not allow 100% until you buy the key (you can use up to 50% in evaluation mode but then all the other deco stops (to 40') will use the 50% deco gas). Suppose you are diving on air and you set your shallowest deco stop to 20' (or even 10'), how do you adjust the air deco time for 20' if you plan on using 100% there?
If someone even has formula or algorithm for this, it would be greatly appreciated!
