The moderators, and elder moderators developers, cannot manually change your rank, so you will have to play more games.
The system works by taking a 15 game window. Each game gives you a certain number of new ranking points, once you’ve established a stable rank. The approximate values of the new rank points are here. However, if you have a win against a far stronger opponent, and your new game takes that outside of the 15 game window, and replaces it with a weaker opponent win, then your rank will go down by the difference.
As for @springyboard’s question, correspondence timeout wins are annulled as follows:
If a player times out of one (1) correspondence game, it will count. A “Has recently timed out of a game” thing will come up under the player’s profile. The marker goes away once the player concludes a game by resignation or scoring. If the marker is still under the player’s name, then all subsequent correspondence timeout losses for that player will be silently annulled. This is to prevent rank from being lost by mass timeouts. Chances are, if you win a game by timeout and don’t win rank, it was because of this. These games do not show up as annulled at all, and still show on the rank chart, but their rank point difference is set to 0.
Hope this helps!
Also the person in charge of OGS is anoek, but he probably gets so many messages, and he can’t do anything about this, so DON’T CONTACT HIM ABOUT THIS.
