George,

Thanks for the great discussion on deco diving.  I have a few questions. It 
certainly breaks our paradigm and also  changes Mr. Hamiltons quote of "what 
works, works" to "what works, George can make better.

Will the "80% in atmospheres" starting point for decompression be the same 
regardless of the max depth of the dive?  Most of the gas dives I do are in 
the Great Lakes between  150ft and 250ft with bottom times between 20 and 30 
minutes.

Since the 70' stop is maxed out on time to take advantage of an open Oxygen 
window,  Do you max out your time on the 100' bottle as well if you are using 
it?

I think I misunderstood your answer regarding breaks as deco time.  If I have 
a 30 minute stop at 10' and I take a 6 minute break is my total time at 10'   
30 minutes or 36 minutes?   (I was taught 36)

In rough, open water conditions how would you adjust your shallower stops? 
What about preconditions such as really cold (40degree) water?

Finally, If I am doing repedative dives at shallow depths (above 100') what 
changes would I have to make to my profile if I was diving air on the reped 
dives?\


Thanks again for the patience with the less experienced.  I appreciate it.

Rich
