GF's on Shearwater and Vision

Last stop is at 3mtrs, of course you can do it anywhere between 3 and 6, it seems to clear in about the same time but I've only been diving profiles resulting in 5-10minutes at 3/6, on deeper divers I guess the difference would increase.

FWIW I dive "sloppy 6s" as taught to me when I did my Gas course with the much missed Keith Morris, I think he pinched it off someone else (typical)

Sloppy 6 plan is when you run a plan based on final stop at 6mtrs, then final stop at 3mtrs and compare the difference.

On a 6mtr plan the final stop might be 25minutes, on the 3mtr plan the 6mtr stop is 8 minutes and the 3mtr stop 17minutes... generally/roughly they have the same total (again on radical dives this starts to fall apart but the logic remains (I guess? ))

Then when you dive the profile you do your set 8minutes at 6mtrs, then you split the remaining 17minutes over 5, 4 and 3mtrs, for example 5 at 5, 5 at 4 and 7 at 3 or some similar pattern.

I doubt there is any good reason for this but I figure its an extension of "flying the curve" and my shearwater doesn't seem to mind
