Thanks, found a table on this site at the link:

Question, is the traditional definition of bottom time used in this case, that is the time from leaving the surface to start of ascent or does it include the entire time immersed?

Looks reasonable but I wonder what decompression algorithm and empirical testing the table is based upon?

One direction would be to go to a free diving deco meter such as is under discussion at: http://forums.deeperblue.net/freediv...suunto-d3.html

Looking into the Oceanic Geo now. Even with that though precautions for reducing residual nitrogen in apnea make sense. Other ideas out there?

Thanks
