O btw, I thought i should mention my blitz rating.
At our club we have 30 min games each side on monday and saturday. My rating for that is 1541. Everyone bugs me because i suck at blitz. They beat me during the 30 min games and have ratings of 1800+ for the 30 min games but for the actual OTB games which count with 2 hour timers my rating is 1700 and their is 1700 to 1800.
It annoying that we have similar OTB ratings but the blitz ones, their ratings are 300+ points more then mine.
So playing 10 min blitz, my rating would be______? And i'm scoring 82%+ in my loses on CM10000 and not CM9000. Ponder, Ponder.
BTW fritz doesn't give you agreement % like that.

Originally posted by RahimKSo, I guess the agreement % is not actually a factual basis to caculate performance ratings? Then, do you know how to caculate performance ratings in a single game? I would love to be able to do that! Then, I could calculate it for twenty of my serious games OTB and see what my rating is overall by average.
I ran a morphy vs another gm into CM10000 when i first got it and the agreement for morphy wasn't 100% more like 90% some. When your playing weaker opponents its easy to find good move because they can't play at you level.
Anyways, your can't use the chessmaster % agreement like that. 2-3 years ago when i was, i'm guessing 1400 OTB I used to get agreement ...[text shortened]... utes each side. Imagine if I had put in my rhp games or OTB games. Ponder over that will ya.

If you are talking about one game, no way.
But 20 games, it's done all the time. For each game, take the opponent's rating, and add 400 for a win, subtract 400 for a loss, and add or subtract nothing for a draw.
Now take 20 games in a row, and average what you come up with each game. That's your "performance rating" for those 20 games.

Therefore the performance rating could not be translated into a true OTB rating.

Originally posted by RahimKNo, I mean overall. I mean, if you can measure your performance rating over 20 games like he is saying against a computer or a human - either one. Now, do you know of any list anywhere (sanctioned) that has a USCF rating for each chess computer? Someone who researches it and rates the computer? For instance, where I could look a particular handheld chess computer up and see what its USCF rating is by research even though the maker perhaps did not do that research but only gave an estimated rating?

Its at chess.ca click english, click on ratings at the left adn then rating calculator at the bottom of the page and enter the stuff. I think it you can only enter 12 game results at once.
As for computer ratings to Uscf, no idea. On CM 9000 which you have I belive I got a rating of around 2100 and my friend has a rating around 2000 and he's 1650 CFC, 4 years ago when he used to play in tournaments.
So CM rating - 350 points about?
