the big push for me happened when I was AI for a lot of scuba classes at the university. I would run on average 100 dives/semester *4 dives/day, 8 days of diving ish per class, and typically 3 classes* just in training dives with them. Add that to a bunch of personal diving and I was pushing 250/year and that lasted 3 years. I had stopped logging those due to not having a computer that downloads them, but now that I have a Petrel it is doing the work for me, so I'll go in and put a quick note in there. The biggest thing for me is bottom hours, especially now that most of my diving is well over an hour, it's a far cry from the quick training dives for OW that are 30 ish minutes with nothing really going on for me.
I'm up over 1k dives in the 5 years I've been certified, but like I said, the first 700 ish were a lot of short shallow stuff, and while I have hundreds of hours of pool bottom time, I don't bother logging that either. The curve has slowed considerably for quantity of dives, but the duration has increased drastically and that's what matters.
