If your min_dev is excluding all tokens between 0.35 and 0.75 as being
unable to influence a ham/spam decision because they are too
inconclusive, then it follows that a combined ranking within this range
is also ambiguous.  If a message classification of 0.55 is definitely
spam, then an individual token ranking 0.55 should also be indicative of
spam.  This is an inconsistency to profess on the one hand that 0.55 is
dubious, but on the other hand to declare it conclusive.
