Isn't there actually _two_ z scores? "how much does it look like ham"
and "how much does it look like spam"? (I might be mis-understanding the
code here). In this case, isn't the scoring going to need to handle
"hey, both are greater than X sdevs, set it to 50%"
It seems like you'd actually end up with two cutoff numbers, or one
as a difference from 50%...
