Self-adjusting bogofilter.cf settings

[Mark Constable]

I'm curious to know if there is any software, or idea(s), out 
there on how to automatically adjust and optimise bogofilter 
settings ?

If not then, for instance, if a one line summary of the current
wordlist.db settings could be logged daily then surely some
_obvious_ (if they exist) trends could be analyzed, and according
to some _obvious_ rules, write out an optimised bogofilter.cf ?
