As I said before, within certain limits it doesn't play any significant rule. >2)Shredder6 can easily be top, if it gets to play any lower rated program such >as crafty, since there is no rules as to which program gets to play which >program how many times (there is no such rule in SSDF AFAIK). Any lower rated? I still don't get why that should be a fact. Lower or higher rated has nothing to do with it. BTW, SSDF avoids games where the difference in the players ratings are very big. 100 ELO is however well within that limit. >> >> >>>We are talking about 107 game here... >> >>We can agree on that playing 107 games against only one player is not a good >>idea.

The number one in the list has to play only lower rated and that doesn't make any difference. >(refer to point 2). > >cheers, >pavs > > >ps, I am not trying to imply that SSDF list is BAD, but what I am trying to say >is that tere seems to be a mistake in the method. >I too enjoy the rating list as much as most others. ;)
