That's not what you have said in the past.  Look up your statement prior to the
last WCCC event.  "Falcon beats all commercial engines in my private testing"
(paraphrased, but semantically identical.)

That is _not_ the same thing as saying "sometimes I win, sometimes I lose..."

It isn't what you said previously in this thread, in fact...

quote on

"as Shredder 8 is the only engine that consistently scores above 50% against
Falcon in my tests."

quote off

If shredder is the only one that consistently scores above 50%, then the rest
score 50% or worse.  I'm not convinced of that unless you have a configuration
issue, a bad book for the commercials, or something else...

That was my point, any my _only_ point.
