I see nothing puzzling about it.  Here we see an Elo difference of 33 points:
    Program               Elo    +   -   Games   Score   Av.Op.  Draws
 01 Shredder 8 UCI      : 2828   43  42   248    74.0 %   2646   19.8 %
 02 Shredder 9 UCI      : 2795   40  39   245    71.2 %   2638   27.3 %

and error bars athat are about 80 Elo wide.  So Sedat's list does not decide a
winner between the two.  Probably, the other lists don't either.

Couple that with the different conditions of the different tests, bolt on the
difference between opening books, and stir in CPU, hash file differences and
what have you.

Nothing surprising in the least (To me).
