Even if your traffic patterns are different, the hit rates shouldn't be that low. There would be a difference if your MTA uses a DNSBL to reject or if you apply other pre-content filtering techniques.
It's not a matter of different traffic patterns as much as a matter of when I do the tests. Incoming mail that is accepted is subjected to many tests before it is even checked against the new domains list. If I put it closer to the front of the tests it would probably hit higher but I've never had much need to do so.
