vim for the win! I’ve been using it so long that I can’t think about what I’m doing or else I get confused and it all falls apart.
Is the site’s code open source? I wouldn’t mind contributing some on GitHub if I see any bugs I think I can handle.

I believe 0 is 30k, so you’d be a 7.666 Dan (since 0 isn’t a rank)
I’m pretty sure the source is here (I haven’t explored it yet):
Yep, although note that your rating will change too so this isn’t necessarily where you’ll be exactly
I went back to the beginning with this revision to make sure a log fit still seemed to make the most sense, and to do this I setup an interpolator optimizer to spread ranks apart until we started seeing some fairly consistent win rates accross a few handicap stones accross the ranks, this got me some data points that looked like it was basically a log fit. From that starting point I computed something like 20,000 different combinations of feasible parameters and then sorted them in various ways, mostly around how well they aligned with our org ratings and how consistent the win rates were
but I’d imagine there hasn’t been much in terms of rated games in the AGA (or maybe there are and I just haven’t figured out how to do them ), how would you like us to fill this out? I’d imagine best guesses, but I personally (and I’d imagine I’m not the only one) self-promote based upon my success on OGS, so I could put in my last tournament rank, but it’s been a while and might have been considered a bit suspect when I had it
Yeah that is true. If you have your ID in there though it’ll help with future updates as well, in a more automated fashion. But yeah, the covid years isn’t the best time for this. Still, we work with what we have, and since AGA ranks for everyone are basically on pause, at least everyone is on pause together so we can still have a useful mapping - albeit perhaps that will jump a bit when AGA rated games start pouring in again.

Are the rating changes solely due to bug fix? Or are ratings systematically shifted down to balance for the new conversion.
However our SDK and DDK, and high dan ranks, diverge a bit more from both organizations. Generally speaking you will have a higher rank on OGS than either organization in the low SDK and DDK ranks.
Just to be clear, does this mean that after the adjustment scheduled tomorrow and before the dust settle down, people at about low SDK and DDK ranks will see themselves on a higher rank on OGS than on AGA and EGF, averagely? Like, maybe 10kyu on OGS while 12kyu on EGF?

Yep correct

Ratings will change because of the bug fix and also because the rating to rank conversion formula changed, which affects how much opponents ratings are adjusted in handicap games, thus affecting your own rating progression. That being said, the shift isn’t that dramatic in ratings usually.
Thanks!
Appreciated your clear explanation! Waiting to see it gets implemented <3
Hmm, I have a rating of 1525 and am 12k at the moment. With that formula, it says I’ll have a rank of 24.68. Does that mean I’m moving to 6k?
Your rating will change too, but you should expect to be SDK yes
we removed our sliding windowed rating system, which means things will be a bit more intuitive now - if you win, your rating will go up, if you lose it’ll go down.
I’m glad they are changing that, since it is pretty frustrating beating a weaker player and losing a rank because of it.
This sounds like an extensive and well researched update. Plus, it has been communicated well. So thank you to the OGS team for all the hard work in that respect. I’m excited to see how the new system works out. Now, let’s play Go!
Note that only players who reached dan before the update can claim to have True OGS Dan rank (and Ultra Rare OGS Dan for pre-Glicko dans).

And one might want to to have some screenshots or chat logs to back it up, since it’s being retroactively applied
Yep the updates are retroactive
