Avg Rating for the top 4 programs = 2436.

If DB had a 90% (+36 =4 -0) score against these programs,
then the DB rating in comp vs comp games would have been 2824.
It's TPR against Kasparov was 2862 (human vs comp).

Here is current SSDF list

2 Junior 6.0 128MB K6-2 450 MHz       2689   31 -30 565  68% 2557
3 Tiger 12.0 128MB K6-2 450 MHz       2671   33 -32 486  64% 2572

97 DB would still be the top rated computer at 2824, however,
the difference between 97 DB and the current #1 would only be
about 100 points or about the difference between the current #1 and

8 Crafty 17.07/CB 128MB K6-2 450 MHz  2624   46 -44 251  62% 2541

It would be very interesting to see the ratings for multi Fritz
or Deep Junior on 8x-700 HW.  :)
