Very high automatic automatic rating

Most casual players appear to have "1500?", which I take to be a conditional rating, which changes when they start playing actual rated games.

For some reason, mine reads "2200?", which is insane, and I think means that much higher level platers pick up my challenges.

How did this happen, and can it be changed?

5 years ago you won this rated game. That made your provisional rating go from 1500 to 2200, and has stayed the same ever since.

Going from 1500 to 2200 just from a single game against another "1500?" is still very weird, though. I'd have expected 1700 or even lower, considering the other player's rating was highly uncertain at the very least (it could even have been the opponent's first game).

Unless the opponent won other games while this game was going on, and the rating calculation used the opponent's rating at the end of the game rather than the start (I don't know if it does, but it would make sense). Beating a 2000 in your first game might be enough to get to 2200.

I believe this is exactly what happens.

Thank you, folks. I've got one running now, and my expected loss should start pulling me to a more realistic rating. That and some blitz games, which terrifies me, but I really need to start doing.
