    I read the FAQ section on ratings, and I have a follow-up question:

    When ratings are calculated at the end of a game, which rating is used, the current one when the game ended or the one when the game started?

    In a hypothetical situation (based on real events):
    Ratings at Begin of game: White 1400 - Black 1700
    Ratings at End of game: White 1450 - Black 1500
    White wins.

    The ratings would change to 1477 (1450+27) and 1473 (1500-27), respectively, if the beginning ratings were used (which seems the logical choice for me).
    But, if the current ratings at the end of the game were used, the ratings would be 1468 (1450+18) and 1481 (1500-18).

    Which one is it? And, perhaps more important, why?

    Thanks!

    It is done at the end. Why? Either way it has it's advantages and disadvantages.

    Example, people complain when ratings go down. If it were done from start, people would complain that a rating went up.

    LOL...Sorry I can't help but laugh...Just wait till you play a 1200P who is rating is actually 1800+....I have lost as much as 32 points...Should never happen when the person is still P rated in my opinion.

    It has to be one or the other, both systems are flawed. I think the site was asked in a vote recently (?) and overwhelmingly we voted for ratings at the end of the game not the beginning.

    It has to be at the end!

    Just suppose the calcuation was done at the start. Say, I'm an unscrupulous rating whore. I resign a number of games to get my rating down to 800. I then issue 100 challenges against 1400 players, which presumably I would win most of them, lets say all 100 (for ease of explanation), I would get 32 points for each win, so 32 * 100, means my rating would be 4000, which obviously has absolutely no bearing on reality.

    LOL...As your rating went up, the amount of rating points your would receive would go down of course

    You still wouldn't receive 32 points for each game you won, it is going down each time...I must be missing something in the point you are trying to make

    My post could be a little unclear. I meant to say if the rating calculation was done using the ratings at the start, as opposed to "Just suppose the calcuation was done at the start." Of course, the calculation has to be done at the end due to the necessity of there being a result. I didn't explicitly state that as I thought it would be understood.

    Remember, the idea here is a game based on STARTING points.

    All the games would be 800 vs. 1400 apx. Therefore, they would all net about 32 points resulting in a lopsided rating. This is a point I forgot when I first answered this thread.
