Thanks Pete.
Warm up is stretching and some negative holds until my heart slows. Get in the water, on my back, 2, 3 and 5 minute holds, a 2' packed hold, 5' vent, a dozen fast exhales and pack about 25%.
Nothing new in training. I hit some very good times in spring when my dive buddies were training for Cyprus. Then a good friend spent a few months here and we dove a lot. Training from mid Sep was a target CB, a target FI, a CO2 table, an O2 table, a max static dry and a wet static, each week.
It's hard to say how much more, but as Eric warned, the gains now seem to come more from technique. Since I haven't flown a 747 for over five years, that would be a nice number for a PB, don't you think?
Aloha
Bill
