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!

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

Originally posted by AudioRaptureIt 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.

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.

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.

Originally posted by Very RustyRemember, the idea here is a game based on STARTING points.
LOL...As your rating went up, the amount of rating points your would receive would go down of course 😀
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.
