That was my original point. The "new player in town" is not going to be >2600 to start. He works his way up. It shouldn't matter where he starts as long as he doesn't get a rating until "enough" games has been played. But since these testers has a pretty good idea that new program x version z is better than the old version, it makes good sense to start out against the top. The only "problem" I might fear here, is the program x version z was built to beat program y version w, then latter comes along program y version q, built to beat prog x version z. This kind of inbreed might lead to artifically inflated ratings, but I don't know much an issue this is, they seem to do really well against much lower rated programs also. >>>>If shredder7.04(A1200) starts by playing 20 games against palm tiger14.9 and >>>>20 games against Fritz3(p90) then I doubt if it is going to make it's rating >>>>smaller. >>>> >>>>It has good chance to get 100% or almost 100% score in these games. >>> >>>But one draw will cost it rating points that it won't make up with 19 wins. >>>The other point is that as it beats palm tiger, palm tiger is going down in >>>rating also, which will mean that others that beat it will see a smaller >>>rating improvement. >> >>If palm tiger's rating is going down then Shredder7.04's rating is going up. >>I agree that in this case other that beats palm tiger may get smaller rating so >>the influence is for both sides but I do not see a reason to assume that the >>influence for going up is higher. > >Simple.

Sure, but how does this indicate inflation? There is less margin for error if you have a really high expected score, natually, but if you've earned that high rating through enough games, it shouldn't be a problem. -S.
