I used to use the SSDF tables to make "pretend" tournament tables of the computers/programs I owned or was interested in, all play all 40 games, by extrapolating ssdf results. There was always holes, or Genius 4 was leading Genius 3 3-1 giving me a 30-10 result, or Genius 3 P90 loses to Genius 3 486/50 9-11, always spoiling the logic of the tables. The major finding was that although a program may have been ranked 1 on SSDF, it would often be 3rd or 4th when only it's games against top competition were considerred. The extent to which a top program flogs a minor progam can effect it's postion amongst the top few too much in my opinion. eg another partial copy of November list Rebel-Tigger Results: MCPro 6.0 P90 17-3 Fritz 3.0 P90 25.5-2.5 Don't mind me, I'm just raving here.....
