I'm slightly disappointed... I thought these would have to be rather
interesting to score so highly for you, but alas they are pretty
normal. My scores are:

I don't keep many emails around, but I think maybe I'll scrape together
whatever is saved in my client to test some numbers against... do you
have a simple procedure for running bogofilter on a bunch of emails and
collecting the results? A script perhaps?

Again with the bogotune... considering how just about everyone involved
in bogofilter has expressed how they aren't entirely certain exactly how
the various algorithms actually work together and why changing certain
values one way or the other has the effect it does, an aweful lot of
faith is put into bogotune to magically come up with the best numbers.
Admittedly, I haven't cracked open the source on it to audit the
procedure it uses, but to me this constant reliance on it despite
contradictory claims seems slightly out of place. Maybe, just maybe,
bogotune doesn't produce the best possible numbers. Maybe it finds a
local maxima instead of a global one. Just my opinion, I could be
