According to my other post here on a different matter, Rankings explanation? my ranking may be incorrect and a admin needs to correct it according to other users??

To any mod looking at this, I would say that these two wins are what is seriously distorting Jamie’s rank: Play Go at online-go.com! | OGS & Play Go at online-go.com! | OGS and annulling both of them may resolve the situation.

Sorry if I messed something up here, as a beginner I am still getting used to the site.
Thanks for the analysis @Kosh
I annulled those two games, which were clearly “incorrect results”.
@JamieCropley’s effective rank now looks more reasonable, though TBH I’m not clear why the series of losses hasn’t driven it down further. This may warrant a look from @flovo and @anoek .
In addition, there’s still a residual bug from the recent update where the person’s display rank stays high for a while after annullment, but you can see their actual rank on the graph and in the game history.
I guess we’ll iron these things out in due course - thanks again for the help.

Upon closer inspection, it seems that a loss against a high ranked person while the uncertainty is high (the first couple of losses) actually increases the effective rank, because while the rank itself may go down a little, the uncertainty drops a lot, and humble rank increases… or somefink like that.
Still worth someone more meticulous with maths than me taking a look

The most recent game_id 31027382 he lost, but his rating went up from 1065 to 1212. I don’t think that’s right?
Here is the game in question, Jamie resigned after just one move (in chat he explains). I don’t know if that means the game shouldn’t count, but still his rating should not have gone up.

Losing against a much much stronger opponent actually shouldn’t change your uncertainty a lot because the loss doesn’t add much information to your rating.
Losing against AlphaZero usually (almost) doesn’t tell you anything about your strength or the uncertainty of your rating.
As far as I know the Glicko system takes care of that anyway.
Getting to the bottom of this might be not trivial. So I think you have to be patient here.
I wonder if it’s something to do with handicap games.
I never found out if this was reported properly and or addressed?
Hopefully it gets sorted in some way, but to me it seems correct anyway for how it’s been explained so far so I will stop worrying about it unless someone replies in an official support capacity.

Quick question: where is the humble rank actually used?
I’d expect:
- for kyu/dan display next to the name
- automatch
- maybe handicap calculation
