Did anyone's rank / rating jump recently?

During the last correspondence game I was playing I noticed my rank jumped a good 4 stones as well as my opponent. I thought it was a glitch, but it seems to be staying. I feel uncomfortable suddenly being an SDK.

Has this happened to anyone else? Was there some change to the scoring system?

Yes, many people had their ranks adjusted in a recent update to the rating system. More details here:


Ah thanks, I tried searching and only saw the 2020 update for some reason.
