Ken, you are obviously far beyond me in terms of diving and experience, and maybe this is a minor semantic point in light of the fact that someone has lost their lives. But I think that if you are going to try to analyze data in a scientific fashion, then terminology is important because what a dive is labeled has implications for how aggregate data is sorted (as was pointed out above).
I'm pretty sure that everyone reading this thread understands that a 300 foot dive with a rebreather is different from cruising along a Caribbean reef at 40 feet. But the fact that in the vernacular, the term "recreational" is used to refer to a dive without a staged deco obligation doesn't change the fact that that usage is incorrect, and that using it in reporting contaminates a database. So I stand by my pet peeve against using the term "recreational dive" to mean a shallow, basic OW dive with no required deco stop (of course, every dive is a deco dive, but that's for another thread!).
Yes, if you pay someone to get your car keys from the bottom of a lake, I consider that a commercial dive. And if you push thousands of feet into a cave using a rebreather and scooters for fun, that's a recreational dive...
