I don’t think chat ranks are accurate. They’re close though, so it’s a bit confusing.
Look at old review request of mine.
7k vs 8k claimed but in chat I’m listed as 5k in messages. But when we look into api we see this:

30-22 = 8, 30-23 = 7, it matches! So old elo ranks are stored in games, indubitably.
