Draw whatever conclusions you like. :) From a stats standpoint,
these are actual results. :) I do not work for any of the
s/w companies, so I have no insight why a program performed above
or below expected levels. Put pressure on the companies that sell
the programs to get more exposure with humans. I can support that. :)
I should also mention Rebel-Century, no SSDF data though, but over
20 games with FIDE rated humans on 350 to 600 MHZ machines:
FIDE
TPR
Reb-Cen PIII 500 2593 (includes last ISR game!)
Again, sorry that the latest s/w on the latest hardware against
the top GM's is not avaliable. I wish it was, but this is what
we have. The SSDF does a great job providing us very good information.
No rating is exact or static, so expect fluctuations and changes. :)
My view is that chess is chess. :) You may disagree. :)
Best Regards,
