Stop it with that understanding how it should work rubbish! These people have planned at least two dives with different GF lo on a variety of dive computers and concluded that GF lo doesn’t make a difference.I would say: the deepest stop is only determined by GFlow as by definition it applies at the depth of the first stop. GFhigh is irrelevant for that as it applies at the surface and thereby at intermediate stops, stronger for the shallower ones. At least that’s what we do for the subsurface planner/ceiling calculation. But as long as you are doing NDL dives, considering gradient factors is pretty much overkill. You could slso add conservatism by only staying dome percentage of your NDL. They are only relevant if you want do shape the profile of your deco stops which you don’t want to do.
We don’t want any of that proprietory nonsense here, we want public domain, open source stuff to match our closed source computers. So away with you and fix it to be like the computers, not like it should be. And don’t be stealing our NDLs either.
( in case that’s not obvious)
