Hi Tom,

As a guess, you're tuning with a small wordlist and small sets of ham
and spam messages.  How big are they (the wordlist and the message
sets)?

bogotune applies some boundary checks to the ham_cutoff it recommends.
It won't recommend a value less than 0.10 or greater than 0.45 for
ham_cutoff.

More later,

David
