notabob once bubbled...
Correct me if I'm wrong, but unless my reasoning is off, making progressive stops only makes sense once a diver is shallow enough that he/she starts off-gassing. Typically about 30ft, is it? As long as one is deeper than that, the nitrogen intake does not stop, though it does slow down at the shallower depths.

30' has nothing to do with it. On our last dive, the first deco stop was at 130 fsw, offgassing started at 136. The offgassing depth depends on what you are breathing and how deep you've been.
