Good morning
I have a question that I can't solve related to deep stops.
During my training I have been tought about the rule for deep stops: (depth+6m)/2, meaning if you dive at 30m, your first deep stop is at 18m for 1mn, then (18+6)/2 second stop at 12m for another mn, then 3mn safety at 6m.
What was the training? PADI, IANTD, TDI etc?
All that is without decco.
Unfortunatly sometimes applying this rule led me to reach decco during the deep stops -as if starting the ascent with 1 or 2mn before decco- that I, may be, wouldn't had if I went directly to the safety 6m.
So my question is: what is the best? Deep stops as it allow more off-gasing but some tissues continue to saturate, or going directly to 6m?
The framework of this question is recreational dives around 25/30m (air or nitrox).
Not sure where this plus 6 rule has come from, really a new one on me.
For a 30m dive on Nitrox 32%:
I would make 9mpm acsent to 15m
The slow to 6mpm or 30 sec stop 30 sec slides for each 3m increment.
At 6m take as long as possible to ascend to the surface.
I tend no to do physical deep stops for dives deeper than 30m rather change the acent rate at a certain depth. But this is the basic forum, so I'll not go into detail
