Jarrett:
Are there stats to prove this? Was there an increase/decrease? Did it stay the same?
In my opinion, there are far to many factors that interact to conclusively say computer had this effect. For instance:
1) Lowering of training standards over the years
2) Increase in numbers of divers from many different backgrounds, including may high risk catagories
3) 'mainstreaming' of fringe dive activities - Cave - Tek etc
4) Advances in Deco Theory - models
5) Increase in the number of vacation dives resorts/liveaboards (IE increse in total dives)
6) Mainstreaming Nitrox and Trimix
7) Introduction of higher reliability gear - SPG
8) Depending on how far to go back, introduction of single hose reg, BC, Octo's etc
9) Modern Dive Today programs
In essence, my point is that singling out a single piece of gear and claiming it had this impact on DCI rates or totals is a bit simplistic.
