You can have this opinion, but what data do you base this on. I have played both
ways and see nothing strange in my results going for one computer to two
computers in the chessbase interface.

I am finding the results sounds, and feel that they are accurate representation
of how the programs will perform against each other on two computers.

I have been able to accurately predict the placement and approx. elo of programs
before they show up on the SSDF list with the data generated in this way. I
don't think this would be possible if the data was scewed in a big way.
