I get 1 false-positive every 3 moths on average, which I fix by adding the address to my whitelist. I get one SPAM message every 2 weeks that makes it through on average, for which I make a new rule, if possible.

Yes I do once or twice a week. It goes very fast as I can easily spot them, the very few there are, as said, maybe one every few months. You can set the filtering threshold to a number. Mine is very aggressive so it is bound to catch more false-positives, yet so far it has not.
