Does Blue Angel have time limits on the dives? The boat run time of 3 hours in the morning and 3 1/2 hours in the afternoon does not give much time for travel, 2 dives, and a reasonable surface interval. You said you were diving 100 cf cylinders, that could make for reasonably long dives unless they are limited by time.
My previous comment regarding O2 limit may unduly reflect my own experience with longer and deeper dives. You could do seven 1 hour dives to about 50 ft avg depth on EAN 32 and just stay under the 24 hour O2 exposure limit
Blue A kind of has a time limit on dive. They are DM lead, it is rare (when I was diving with them) to get a dive over 1 hour, most were 45 to 60 minutes. I was not diving 100Cf, and I did not see one at BA. I though SI were a little short about an hour, they would make the first dive the farest from BA and part of the SI was use coming back toward BA so trip back was quicker after last dive.
