This is from my personal machine, which handles my mail plus a couple of friends. It covers from the time the logs were rotated (Sunday morning) until present.

4820 messages processed (15366769 bytes)
39.48% of them were spam (1903 messages, 10718516 bytes)
318 minutes and 34 seconds of time spent
169 minutes and 54 seconds spent on spam
148 minutes and 39 seconds spent on ham
3.97 seconds spent per message on average
16.97 is the average spam score
3.57 is the average ham score
8.86 is the average score overall

The stats for my account only are:

   Total messages:    569
     Avg Score:       16.65
     Avg Size:        5622
   Spam messages:     480
     Spam Pct:        84.36%
     Avg Spam Score:  21.36
     Avg Spam Size:   5454
   Clean messages:    89
     Avg Clean Score: -8.80
     Avg Clean Size:  6527

Note that I run spamc/spamd and don't call SA from MailScanner. I also sort list mail before I run SA, so the total message count would be MUCH higher, with a lower spam percentage if I ran all list mail through SA also.
