If you mean longer time controls then that’s definitely helping, but most games are 5 minutes or less simply because players are going to be able to fit far more such games per day. Similarly the average rating is quite low simply because everyone starts terrible and most people quit relatively quickly.
If we’re talking about the average game you simply need to look at all time controls to get an accurate understanding not pick an uncommon example and arbitrarily suggest it’s representative of the general case.
Last I checked, 55% of games on chess.com are 5 minutes or less if that’s what you’re asking. But at this point I’m just done with this conversation.
Also, average account ELO was ~800 not sure if that’s active or just not banned.
A sub-1000 online rated player is frankly a very poor, total beginner at chess, not an enthusiastic club player.
They only publish numbers above 1000, but they still come up with a number before deciding to not publish it. https://www.fide.com/docs/regulations/FIDE%20Rating%20Regula...
Not all clubs follow those rules exactly, but you still need to track sub 1000 to know when people cross it.
See 7.1.2. Ratings aren't tracked by clubs even when players are under this cutoff - all games for rating are submitted to FIDE.
So everyone now has rating above 1400, except if their rating fell under in meantime, in which case they will be removed from next rating list.
