but opponent only gained 1?
I don’t think your statement is correct. Or please pinpoint which game you are talking about.
Link to the game? “game 1978” doesn’t mean anything to me.
Oh I see. That was after she had resigned many games. Maybe a moderator annulled these games manually but her rating hasn’t been recalculated? Or is it a bug of the rating system?
There’s definitely an “anomaly” there - nothing that normally happens that I’m aware of would cause that, including normal moderator annullment (which results in everything being “just as if” the game in question was unranked).
I suspect that a bulk operation had to be performed manually on her account for some reason, that left it’s trail there…
… or as yebellz suggested a display bug due to so many darn games ~ nah that doesn’t sound right, because the subsequent rating builds up from there.)
Well, if you time out in more than a thousand games, strange things happen to your rating.
Sofiam’s first line in her profile is: don’t trust my OGS rank.
However I would have expected a gradual downward curve.
Actually, that should not affect her rating much at all if the old, correspondence, serial-timeout rule is still in effect. Does anyone know if it is?
Yeah - in theory only predictable things should happen to your rating.
Exactly: what we are seeing does not appear to be a result of normal processes, because of the size of the change in one game.
