As they say in the classics, "your mileage may vary.".  I've had horrible luck
and my OSBF score distributions are what a very kind person would call
"bimodal".  I get a huge blob of scores below zero and a smaller, rounder blob
of scores above zero.

Yes.  In fact, the osbf classifier also has a DC offset of about three.  I need
to spend some time on integrating graph generation in my antispam system so I
can track how the scores are going south.
