And now I won another game and my rank went down AGAIN

[shinuito]

Is there not a bug/typo in the volatility or did that get fixed?

Wasn’t one of the intentions of the recent ratings changes to stop ratings going down after a win. It’s too confusing, enough people don’t seem to like it, so it’s not worth advocating for in my opinion.

With the 15 game block system, we were updating the ratings of your opponents in your block, so if you played a new 13k and you lost, but later it turned out they were actually a 5d player, that loss wouldn’t count for very much. The next game you played, your new rating would take that into account. This had some good aspects, but also made it possible for your rating to go down, even though you won a game (for instance if you lost against a 13k, but later they were updated to be a 25k). We no longer do this, so you should no longer ever go down in rating when you win a game (see note* below) (but you will also no longer have an adjusted game if you lost to a 5d who just started a new 13k account).
