There is a sort of "500 hour" correlation here at least in diving looking at the accident figures.
There is a large rise in incidents for "intermediate" divers compared to any other group. These are at a grade and level where they're starting to push a little deeper than before, starting to do limited deco and so on and for the last several years at least are the group that have the largest number of reported incidents.
Its the transition between gentle, shallow no stop diving which seems to be same to where they start to expand their diving. Eventually they pass through that and have learnt lessons and the incident rate goes down again.
Luckily, SCUBA diving is actually incredibly easy and at these levels also has a massive margin for error so people tend to get away with their mistakes and learn from it whereas other activities are nowhere near as forgiving.
