Subject: The Shredder 7 mystery

When testing the Chessbase version vs the Classic version of Shredder 7.04 I
come up with a very strange contradiction.  The Shredder Classic version
consistently shows about a 6%-7% advantage in speed when testing positions.
This also translates to slightly faster solving times with equal hash tables of
course.  The contradiction comes when I look at my Blitz database standings.
The Chessbase version is #1 in my database with a rating of 2493 after 1824
games.  The Shredder Classic version is #7 with a 2455 rating after 709 games.
In fact the original Shredder 7 Chessbase is #4 (ahead of 7.04 Classic) with a
rating of 2469 after 1180 games.
Has anyone else noticed a "weaker" Classic version?  Could this apply only to
blitz games?
