I'm sorry Mike, but there's NO WAY you guys (DIR/GUE) get credit for all that. Most of that has been around since the dawn of dive time. I learned it in Basic SCUBA class. And the rest of it (the EAD and 20% safety margin, etc.) I learned from (Oh my God, NO!) TDI in my EANx class.
There was a reason we all eventually moved to computers. The problem with the old ways was exactly what you spent the no time on -- calculating your average depth. That is the weak link, the part that is easiest to lose track of during a dive. It is also the part that benefits the most from the accuracy of a computer. Why is that so wrong? Know your tables -- definitely -- but use a computer to more accurately monitor your average depth. That sure seems a better method for the diving I do.
See you Sun.
