Folks, i think the poor initial showing of rybka had something to do with my
computer and dual tasking (and rybka not handling such dual tasking well in
fritz 9 gui)

I am re-runing everything on my old computer and already rybka is doing much
much better than what i report below about fritz9. This old computer is only 446
ghz, but i have made it into a pure chess testing computer, deleting every piece
of software that might make demands on its resources. I trust the results of
this computer more (and therefore the results of the fruit 2.2.1. testing, which
were done on this computer). In general, the results on this computer tend to
correlate well with cegt and ssdf results.

Here are the fruit 2.2.1. tests again. the 57% at the bottom was against beta 1,
utilizing the same noomen test set and same time controls

I look forward to the rigourous testing to come from the various lists including
cegt and ssdf
