Although not playing USCF, still keeping my hand in chess with computer and the what not. When I came back, I felt like I was better player than 5 years ago. I had 3 draws against players that were juts baove my rating. So much for feeling like I was better - I was wrong or so I thought. Fast forward to May of this year, I played in my tournament since coming back. I noticed one of old friends rated near 1600. Back in 1995, he was rated over 1800. Hmmm, the aging process is not going for my friend or so I thought. http://www.64.com/uscf/ratings/10159130 During the tournment I kept an eye on his game. His game did not seem any weaker. To make a long story short, one of the other locals started telling me how the USCF systematically too everybody's rating down because of rating inflation. Of course that only impacted those who played. They set floor that were genrally 200+ points below their high. In Roy's case above his floor is 1600. One can see he touched the floor several times. The last year, the USCF decided they over corrected and are now psuhing ratings back up again. You can see that Roy's rating is going back up. Ken Sloan probably understands ratings and ratings systems as well as anyone - this short piece is great: http://groups.google.com/groups?q=g:thl3870583014d&dq=&hl=en&lr=&ie=UTF-8&oe=UTF-8&selm=t766h9mrlv.fsf_-_%40uab.edu This has been discussed at length at r.g.c.p - this thread has of the participants that were actually involved in the USCF rating decisions - there is a lot of mud slinging. http://groups.google.com/groups?q=g:thl286037684d&dq=&hl=en&lr=&ie=UTF-8&oe=UTF-8&selm=8t99ed%24bom%241%40nnrp1.deja.com Marty Glickman and Ken Sloan are, IMO, two people who really understand how the rating system works. Generally speaking, USCF has never had totally neutral rating system - there has always been inflation or deflation parameters at work. Search usenet where Ken Sloan or Marty Glickman are the posters to gain the most intelligent understanding of ratings.
