I wish that I had the time to go, but I'll be in the pool, initiating more lucky souls into the pleasures of the uncrowded north - where the water is cold and the divers are hot...
I am interested in the calculations you are using for your nitrox recommendation. I use the following:
Max depth = (46.2/%O2)-33
Cont. dept = (52.8/%O2)-33
For 36% O2 this gives:
Max. D = 95.3333
Cont. D = 113.6667
Given a planned max. depth on the dive of 100, I would ideally use 34% -
Max. D = 102.8824
Cont. D = 122.2941
If only premix was available, I'd opt for 32%.
I'm probably just splitting hairs, but I like to err on the side of conservatism when it comes to O2 tox.
