Hey, I have an idea ! Let's do some wild speculation in the other direction.....
Let's say that dive #1 = 100', 20min / EAN 32, makes him group K, 15 min later (now group I) he discovers his Rolex missing.....A quick check on his PADI EAN 32 chart shows 13 min. NDL @ 100'.....
Don't get me wrong, I'm not crazy about this profile, but it's not off the charts - 13 min. is 13min., and a Rolex is $$$$$.
More speculation.... He plans a 10min dive @ 100', followed by a 1min. stop @ 50' 3 min. assent to 15' ect.
Somewhere along the way, the plan goes up in smoke, and he get's bent.
Now is he still stupid, or would we be offering our best wishes, and hopes for a quick recovery ?
