Well, I am looking for a different kind of accidents. Nor for ones that could be caused by computers, but for those that could be PREVENTED by computers. So I would take as an evidence simply a statistically significant difference in odds ratio to have a DCS accident with and w/o a comp.
As for the rest of what you said, I agree with most of it except that non-square profile dives are not that complex with tables. In my estimate, approx. 3/4 of all Caribbean dives are done along corall walls (most of Bonaire, Curacao, Roatan, Utila, Grand Cayman off Turtle Farm and Cobalt Resort, etc) when you go one way at 55-75 ft and then return at 35-45 ft. These dives are fairly easy to plan since they could be treated as two square dives with zero surface interval. I bet comps use the same algorythm.
