Howdy Bob,
I've set mind to 10.5 and my average spam volume per last couple hundred
thousand email has been:

70% of all incoming mail is blocked as spam, scoring 10.5 or higher.
2%  of all incoming mail is detected as spammy scoring 6.0 or higher.

So 2% of incoming mail by volume is spammy but get's through.

95%-97% of the incoming spam is blocked depending on the day.

So i've found using a higher score with some custom blackbox rules appears
to have a good enough block rate, with low enough fp rate.

I think it's better to have a lower fp rate and lower spam block rate by
rasing the block score.

Surbl works great.
Some blackbox dns tests lower the score based on the spamminess of the dns
entry for the server.
