Tanya Streeter has published her O2/CO2 tables at
http://www.redefineyourlimits.com/?sm_id=2211&sm_nm=Training&smt_id=7&aPost=
They are pretty similar to Pelizzari's tables.
If there is a "standard" recomendation, it would seem to be
1) Starting breathhold times for both CO2 and O2 tables should be about 50% of your max.
2) O2 tables should include a consistent rest period, on the order of 40%-50% of your starting breathhold time.
3)O2 tables should increase the breathhold time 10-15 seconds with each pass, 5 to 8 passes.
4)CO2 tables should maintain a constant breathhold time and decrease the rest intervals 10 seconds at a pass, 5-8 passes. Initial rest period should be about half again GREATER than your initial breathhold, ie. 1' breathhold= 1'30" rest period, 2' breathhold=3' rest period, etc.
Now, I'm a newbie to apnea tables and I could be completely out to lunch on this stuff. It's just a repitition of what I've so far seen, while attempting not to violate any copyright laws. If anybody who actually knows about this stuff wants to jump in and correct me on any of it, please do. I only post it because I'm recieving email requests for help, which is kind of silly considering how little I know about it.
