Probaly a bad copy

I've seen plenty of evidence on this forum that the Pentax is visibly sharper wide open (at 300mm) than the Tamron, yet the results at photozone.de don't show this.

Tamron at 300/5.6 - Center 1850, Border 1490, CA 1.3
Pentax at 300/5.8 - Center 1770, Border 1570, CA 1.5

Klaus usually doesn't publish tests of bad copies. I wonder what made him decide otherwise in this case...
