No doubt.  I made a change to my procmailrc file to not save spams scoring >
0.97 for training.  We'll see how it goes.

This of course jives pretty well with many peoples' observation (and my
experience) that most unsures are actually spam.  I think I need to adjust
some thresholds to try and reduce the number of spams which get trained on.
