Make quick matches the primary way of finding matches

Not sure I understood you here. Do you mean that, if I win against someone who is 2 stones stronger than me, without handicap, I get more points on my ranking, than if I win with handicap?

That’s what I would expect to happen, if the rating algorithm was a bit more ELO like but…

2020 Rating and rank tweaks and analysis

tl;dr - Ratings and ranks have been tweaked a little, there should be a bit less volatility in ranks now. Ratings and ranks have been adjusted retroactively. Main changes: We were using fixed windows to update ranks, considering up to 15 games at a time to update your rank. When we got to the 16th game, we’d “commit” your rank and start a new block to update your ranks. We now use a sliding window, so we look at your most recent 15 games (up to 90 days), and use that to update your rank, this…

Because there’s this sliding window in the Glicko2 system which is looking at your most recent 15 games/window of 90 days it’s not really clear how a particular win/loss changes your rating.

There’s some small amount of explanations (and further links) here in the docs Ranks and rating · online-go/online-go.com Wiki · GitHub, and more attempted explanations on the forums, but very regularly questions come up on the forums asking why rating is going down after a win.

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

I would like to speak to the person in charge of OGS please. Thanks

Losing Rank When You win

Sometimes when I win games my rank goes down and sometimes when I lose my rank goes up. I think that this should change, even with the rolling average, I don’t think you should ever lose points for a win and gain points for a loss. Even if you gain zero points for winning against someone who is 10 kyu below you or lose zero for someone ten kyu above it is better than going in the wrong direction. Is there a way this could be factored into the new rating system because it has been bothering me…

Ratings moving opposite?

I’m confused. For the past several games, my rating goes down when I win and up when I lose. Am I missing something? This used to happen once in a while, but never this consistently. Thank you.

Rank lost after a win?

Hello, after “win” by timeout against a 25k (he stopped playing - correpondance), i refreshed instantly to see how my rank would evolved and it went from 11.0k to 11.1k ! so a rank losss after a “win” how is it possible ? thanks

etc

So the most I can confidently say, is that the handicap in the game factors into the calculation. I believe it’s supposed to be that for each handicap stone you have it treats you as being a rank stronger in the calculation (someone correct me if I’m wrong).
