Topic: Opponent's rating used to calculate rating adjustment

Hey everyone.
Just out of curiosity, does anyone know which rating is taken into account when calculating the rating gain (or loss) at the end of a game?
I'll explain through an example: I challenge a player rated a lot more than myself. In an OTB game, my opponent's rating would not change throughout our game, so the rating adjustment in case of a victory on my part would be calculated based on my opponent's rating at the time the game starts or, indifferently, at the time of completion. But for CC it is quite different, since my opponent's rating can drop since the beginning of the game, thereby granting me less points in case of a win if the rating used to compute the adjustment were his rating at the time the game ends, rather than the one at the beginning.
Hence the question: is the adjustment calculated beforehand, once the game starts, or at the time of termination?
Thanks to anyone who can clarify...

It's calculated at the moment the game ends.

Yep, sorry, I've been losing a lot of rating lately :-P

Thanks Dave for the reply.

Hi whyBish, it's actually happened to me often, not just in our current game, so I wanted to enquire... ;-)

If things are that way, I believe that it's unfair. The scores at the beginning of the game should be taken into account.
If one challenges a player rated hundreds of points more, the risk he takes should not be awarded, in case of a win by him, with just a handful of points.

Ratings are not rewards or prizes. They're tools for predicting the chance that one player will beat another.
