i'm not sure if i've seen that large but i might have and want to say i've seen a 2000 in the 800's lol but i'm not sure. those often happen when its a kid that's played scholastic a while back and they have a low otb rating from then, but they've been playing a bunch online and gotten a lot better.
Rating Inflation
Sort:
I was 1350 and 1900, but that was a while ago, since I didn't go to OTB tournaments during covid.

Sorry to be the pedantic guy in the back of the room, but I feel like pointing out that what is being discussed here are ratings 'discrepancies' not really 'rating inflation' which is a different topic.
There are so many causes of potential ratings discrepancies. Most often I'd bet they are related to much more play online vs OTB (or vice-versa), or having a provisional rating in one setting vs an established rating in the other.
The old pattern of USCF blitz ratings generally being a bit lower than chess.com ratings may be evolving over time. It's a fascinating topic, really. The pandemic, and increasing numbers of players with severely underrated OTB ratings (related to training extensively online) -- it's had quite an impact on rating systems overall and has kind of changed the landscape of over-the-board play. These days when you're playing in a USCF OTB tournament, you can never be too sure if the 1000-level player sitting across from you truly plays at the 1000-level or if they are much, much stronger than that would suggest.

This is pretty tricky to gauge correctly, since you can list any number as your "official rating". I pulled the list of titled members, comparing the self-reported rating to the chess.com rapid rating.
- Mean: -112.98
- Median: -73.0
- Standard Deviation: 323.8
But this doesn't tell the whole story. There are numerous titled players who have listed implausibly low (e.g. 199) fide/uscf ratings on their profile, no doubt to be funny. But that makes it difficult to actually gauge if there's a relationship between a person's listed rating and their chess.com rating.
Here's what that looks like:
We can see the outliers for both the chess.com rapid rating and the self-reported rating, but most players fall into that large group up top.
When I dropped all the self-reported ratings below 1500 (a rating threshold I arbitrarily chose), the biggest difference where rapid was higher than self-reported was 879. Once again though, this is just the players chess.com has listed as titled players (11,608 players as of this morning).
What was the biggest rating inflation between USCF and chess.com rating you have ever seen? (Pls do not specify username) I've once seen some one who has a chess.com rating of 2033 and USCF rating of 1002.
