pi,

If you're really interested in doing some testing, that'd be great.  What I 
usually do is create a script that sets up the parameters I want and run 
it.  I might try something like:

         dir="test_dir"
         for alg in r f ; do
             #build wordlists
             rm -f $dir/spamlist.db $dir/goodlist.db
             bogofilter -$alg -v -d $dir -s < spam.mbx
             bogofilter -$alg -v -d $dir -s < spam.mbx
         for dev in 0.0 0.1 ; do
             echo "min_dev=$dev" > test.cf
             formail < test.mbx -s bogofilter -$alg -d $dir -c test.cf
         done
         done

I'm sure you get the idea.  Anyhow, setup the mailboxes, run the script, 
pick the best results.  There are other parameters which can be tuned for 
optimal results with _your_ email.  If you're interested, let me know.
