This is one of those grey situations.. say your'e doing a safety stop from a 100ft deep, and you have a mandatory safety stop to do. 3 min at 10-20ft.. well, as you all know, 10-20 ft zone is ALWAYS crowded.. So, chances are, you're a little deeper as you wait for the conjestion to clear.
Say you were at 22ft for 2 minutes, and then at 19ft for 2 minute. Obviously, my computer doesn't register the 2 minutes at 22 ft, so it'll tell me I still have 1 minute left. But what about the actual nitrogen content in my body? Has the 2min at 22ft and the 2min at 19ft combined effectively done what the 3 minute saftety stop is supposed to do?
I mean, it's one of those "well, just do the full 3 minutes as a precaution and be conservative" kinda situation, but it's good to know what's REALLY going on in case of an emergency. Like, is it better to be deeper, or shallower if you had to dodge a bulge of people?
