massive overnight percentile change?

Sort:
Nkondrick
For puzzles I’m currently rated about 2300. A couple of days ago this had me ranked at roughly the 98.9% percentile. I was checking my stats today, and while my rating is roughly the same, I’m now ranked in the 94.6% percentile. I even have a screenshot from a few months ago where I was rated about 1900 and was ranked in the 95.4% percentile.

Did something just change, like a bunch of inactive accounts being purged from those rankings or something?

Or is that percentile ranking not based on the rating?

Yeah I noticed this in all of my stat percentiles. My rapid rating of 1530 had me at roughly 97.5, and now its ~95%

I just started playing blitz so im only 1150, which had me at ~87%, but now its 81%. idk whats up lol

Same here. Rapid from 95% to 92%, puzzle from 99.5% to 98.5%... ????

there was a glitch in the leaderboards that would exclude some users. i'm guessing they finally fixed it and a bunch of people were added back into the leaderboard

If people were added, why did the global rank change from like 500,000 to 200,000? Doesn't make sense. I would assume that inactive accounts with lower rating have been removed from the rankings.

It looks like it, I was ranked around 490,000 in the world and now I'm 170,000 in the world.

Just commenting for the stats:

Rapid rating 1082: Went from 86% to 79.2%

Seems like they removed a bunch of low inactive accounts, and I suppose this is a good thing because now the percentile estimate is more accurate.

Thanks chess.com

I see that this is an old thread. I found it when I noticed the same thing and did a search. But I'm wondering how you found your puzzle percentile? I can’t find it anywhere!

The puzzle rating percentile is only shown on the mobile app for me. I've never seen it on the website.

BTW, how do you reply to comments on here? Lol

Cool. I'll try the mobile app. I don't know the answer to your question, I'm afraid.

I asked help and support about this and I was advised that there are updates happening with leaderboards and its likely related to that.

I asked what this means and was blanked. No answer. Nice eh.
