New Rating System

I agree. There are some underlying assumptions--like that we don't have paper-rock-scissor situations--that we can only really test by looking at the results.
Here are some of those interesting results. We can do a small case study on ME. I have a rating of 632. That rating is based on 5500 games played against nearly 400 different opponents, with no more than a few percent of my games against any particular opponent.
There are six players (all of whom themselves have thousands of games against many opponents determining their ratings) against whom I've played at least 100 games total--generally several tournament matches and perhaps some league games.... I'll show the expected versus actual against those, and then I'll include my teammate Linda Zsedeney to get a bigger rating range
Larry Wentz (500) expectation, 174 to 69: actual, 179 to 64
Rory Hendrickson (725) expectation, 40 to 76; actual 40 to 76
Dustin Hansen (576) expectation 69 to 46; actual 79 to 36
Bruce Wheeler (610) expectation 62 to 53; actual 67 to 48
Tim Blinn (576) expectation 67 to 45; actual 64 to 48
Gary Dandurand (517) expectation 72 to 32; actual 75 to 29
Linda Zsedeney (434) expectation 55 to 15; actual 54 to 16
These are all close with the exception of games against Dustin Hansen, who has moved up about 50 points since most of those games were played.
Now if you look at Rory (you've already seen he beats me 76 to 40), we can see how he does against a few others. He is a 725, and he's played 38 games against Justin Bergman (795) and 43 games against Dennis Orcollo (813)
Bergman (795) expectation 14 to 24; actual 14 to 24
Orcollo (813) expectation 15 to 28; actual 14 to 29"
