Nice theories, but I don't have any really bad pages, unless you're a literary critic:-) Nothing copied, nothing derivative, lots of high quality organic deep linking.
The penalty is applied pretty evenly across the site, a shorter pages seem to be affected somewhat less than longer pages.
Clearly, everybody isn't seeing the same thing with Panda, but I've taken the time to look into other high-quality sites with low to medium page counts (couple dozen to a couple hundred) that have been hit. I can't lay a finger on anything except that they get ripped off alot and aren't eHow or Amazon.
