This is getting ridiculous.  What Omid was saying was that, in his own testing,
Shredder clearly outperforms his program, while other programs don't.  It's
quite simple, really -- I don't understand why there's a page-long thread about
it.  One can choose to question his testing methods and/or conditions, but the
statement itself was reasonably straightforward.
