Rating question

Hi folks -- didn't see this in the FAQ, so thought I'd ask it here:

What rating is used to calculate the result of a game -- the players' ratings at the beginning of the game, or at the time the game ends?

Thanks, Malcolm

The rating at the end of the game, the current rating of the player.
