Does lichess have any way to show that ratings in a certain time zone are better?

For example, is there a way to show that gmt-5 (US) or gmt+3(COUNTRY) are weaker or stronger. Take a 2000 gmt-5 player, is it possible that gmt+3 at 2000 is stronger or vice versa, if so by how much?

quite unlikely that there would be differences. UTC+3 players play in the morning ans in the evening hence they will play with UTC-5/6 people at at least. So different time zones are not separate pools.

Obviously it would not possible to see this easily. You could take 1 month of games in a zip file and then find games with difference say +-100 pts ans TZ difference > 3 for example then predict expected points and compare it to actual point. I case you decide to do this I would recommend python as language as it has library for everything including PGN parsing

Sounds like you have an hypothesis...

Thanks for the input @petri999 , makes a lot of sense. I think a distribution (edit: in rankings) can be shown by how many actually strong (titled) players are online vs the scrubs (me). I think I kinda figured it out. It would seem that when there's an abundance of high percentilers on vs low percentilers, there's going to be a new hierarchy forming or new percentile distribution happening. I believe this happens at certain times of the day rather than others. It just seemed like an interesting problem to me but I don't know much about statistics.
