2 sets of hit rates follow.

I'll try to find time to send my results on a daily basis as long as the info is useful. As you will see from the message volume this is a fairly small office.

All messages are from the Internet. In other words no internal e-mail traffic is counted in any of these numbers.

I am using the XS as a 1.5 point spam assassin rule in production so it may have pushed some of these over the top. My cutoff score of 5.8.

For the numbers that follow I hand sorted anything that had less than 10 SA points. I rarely ever see a false positives so I'm fairly certain of these numbers. We are very sensitive to false positives so we run a pretty conservative rule base, but I do have some hand crafted rules that have high values that can push a message's spam score through the roof.

The difference in strike rate between days is interesting but it's not the same time period. For the future I'll hit the same time period each day even if that means skipping the most recent data. That should show trending better. Of course it could be something else entirely pushing the first set of numbers up. Only time will tell.
