YET AGAIN ONCE MORE ANOTHER (and last) TIME:

You need more false positives to run a parameter scan than you want to
have in production.  David is quite right: if you use tuning.sh you
should set the target somewhere between 0.1% and 0.3% of the total size
of your test files (r?.ns).  Your own results show that 12 is too low,
as you're getting some reports of more fp during the scan -- and any
record for which the fp count is not the target is invalid.

AFTER you have your s and mindev (and x and cache size and ham cutoff)
properly set, THEN you ADJUST THE SPAM CUTOFF till you have a balance
between fn and fp that you can live with.
