This maybe correct...but I don't think so. More data needed.

I am not sure your claim is correct that Rebel has the best record to date of
any engine. I am sure Junior, Hiarcs, Chess Tiger, and the Fritz will argue this
point with you.

I am not sure what you mean by the best record against humans.

Chess Tiger 14, Hiarcs 8, Junior 6, Fritz 8 have all had 2700+ PR playing
against humans.

Junior 8 and Deep Fritz 8 have a 2800+ PR playing humans.

As far as I know Shredder 7.04 or Shredder 8. The top programs on the SSDF list
don't have any GM games played to data. So to make the statement that:

"the strongest engine in engine versus engine
contests (Shredder 8) isn't, as a consequence, the strongest versus humans."

This statement has no basis in fact. This is pure speculation.
