That’s a dangerous assumption. Cold water divers can, and do, dive too deep and for too long (exceeding no stop times), because of the myth that if they can dive in cold waters they could dive anywhere.
Those who “dive too deep and for too long” do it because they can’t watch their computers for depth and time, not because those dives are beyond their ability, which is the point. And no checkout dive will help identify divers who would then do it on a real deep dive.
