@mghrn55 saidSorry, but it’s really not as simple as that. Suppose a challenge between Clan A and Clan B has already been decided in favor of Clan A, with a minority of games still running. If the Clan A players whose games are still running all resign and the games are flagged as not altering the ratings, this is unfair to the Clan B players who might yet have won their games and whose ratings would justly have been increased by those wins.
But that can be solved by a simple flag.
Any clan that ends after a challenge has been decided can be flagged as an unrated game.
If a player decides he/she no longer wishes to continue a game after a challenge has been decided, then they can do so without changing their rating.
Thus eliminating the accusations of rating manipulation.
My wheels are turning. 😉
Moreover, if some player got into a bad position he knew he could not win, he could just run down his timebank, waiting until the rest of the boards decided the challenge, and THEN resign, knowing his game would get ‘flagged,’ not lose any rating points for a lost game and thereby also depriving his opponent of a justly deserved rating increase.
In other words, not rating some games is also an abusable form of rating manipulation.
Realistically, either every game counts and every game is played out even after a challenge is decided, or there has to be trust that no clan is manipulating the system.
