Tom,

A good question.  One of the differences between Graham and Robinson is the 
counts used in updating the word lists.  Graham has a max of 4 (per word 
per message), while Robinson uses 1.  So, to be totally kosher, one should 
build a database using the same algorithm as will be used when classifying 
messages.

I don't think there's been any research to measure what happens when you 
mix algorithms.

FWIW, my word lists were built with Graham and updated using Graham for 
several weeks until I switched to Robinson last week.  I'm using "-p -e -r 
-u -l" in my procmailrc, and my "correction" script has been using "-S -l" 
and "-N -l".  I forgot to update it to "-r" - an oversight I just 
corrected.  I still have all the incoming email, so I could rebuild the 
word lists, but I've been too lazy.
