I lost rating too at first on ICC, started out very high and then fell. I'm not sure what you suggest to improve that, the first 20 provisional games are not really counted, it's a kind of test games. This is much better than those places where you start at 1600 or something and then use the standard rating scheme from there on. I've sometimes encountered a 2100 dude that was rated 1600 because he just joined, with no provisional period you suffer the full Elo penalty of losing to a 1600. With a provisional period like the one on ICC I would lose maybe a few Elo and he would go up several hundered Elo. My rating is well established so we can calibrate his rating after mine, but not vice versa, this is fair. >The rating system was also changed such that people can calculate their rating >because people in general prefer wrong rating that they can calculate and not >right rating. Sure, we must have a rating we can calculate. Is there a right rating? I don't think so, certainly not for people who sometimes have a bad day or a good day. Say my real rating is X and I have a bad day so I only play like X-delta. Now I lose my next game, his rating goes up and my rating goes down to Z. His rating is going up too much because because I was overrated relative to my true playing strength. The next day I have a really good day and play like X+delta, but my rating is now only Z, so I am underrated. I play and beat some guy, my rating goes up and his goes down. But his is going down too much because I was underrated, he is being punished for me having a bad day yesterday. This is chess, it's not all statistics, there are other elements which make a perfect scheme impossible. -S. >Uri
