For the record, I'm running 100% on about 600 emails if you consider
Unsure to be a no_count result. If you count Unsure, I'm 2 for 600.
Plugging in the archive spam records pretty much wrecked my filter.
So the phrase YMMV really holds true here.
I will probably turn off the '-u' option as soon as I have enough
content to run bogotune from time to time. But I don't want to have my
human influence affect the statistical yet, bogotune says:
The wordlist contains 1224 non-spam and 546 spam messages.
Bogotune must be run with at least 2000 of each.

So that is what it's for.
If I set it to 0.00 will it assume every spam/ham for inclusion to the
wordlist? How low of a value will it accept (significant digits)?
I'm uncertain about how continued reinforcement of tokens being what
they really are would cause their accuracy to degrade. Is it that these
tokens become too assertive as ham/spam for sake of all other tokens?
And as the result of which our filtering becomes similar to just doing
procmails regex filtering on all things /viagra/ to go >/dev/null?
