I do appreciate the original question, but there should be a distinction between working dives and recreational dives because they are very different, from a judging competence standard anyway.
I would think that a pure recreational diver would have hard pressed to dive 100 times a year over the long haul. Even if you had a pond in your back yard, your own compressor, live in dive buddy etc..you would not be able to dive daily, work, weather, health, and other obligations would get in the way, so if you dove for say 40 years, that would take you back to the start or recreational diving becoming very popular, someone would be extremity unlikely to have 4,000 dives. My guess is that that would be an upper limit for number of recreational dives, perhaps some outliers, people who were independently wealthy and had everything that they needed for diving at home so it was simple and easy to splash.
I am retired, living in the Philippines staying at dive areas and in the past year I logged just over 160 dives with a 110 day SI due to lockdown. Without lockdown, I would have topped out at 200. That is about as much as I would want to do, more than that I would start to look at it as a daily chore and that dive time would limit my other recreational options.
I am talking pure recreational diving, not an instructor or guide, these divers can get 4 or 5 a day, 6 days a week or 1,000 to 1,500 a year in a busy shop.
If you look up the statistics, most studies I have come across classify casual divers at less than 8 dives a year, dedicated divers at more than 8 and the average time as a diver at around 12 years so the vast majority of people only get around 100 dives in total. ( Members here are not your average diver, lol)
