Most people I know dating aren't trying to optimize for the number of dates they go one with different people but ideally trying to find that one person they can be with for awhile. So the common definition of "getting better at dates" implies you eventually date less.
I have a few friends in their mid-30s that have become quite the experts at getting dates, but all of them seem fairly unhappy that they are still working on dating rather than in a steady relationship and focusing on other things.
I use dating apps or met a couple of them at the bouldering gym where I boulder.
That's why I stopped going to the local boulder gyms. Too many cookie-cutter "non-conformist dudes" who see the gym as their personal hunting grounds, creeping on the girls like a sleazy tennis instructor and bullying beginner guys because they don't like the competition.
