I tend to look at this in a different light. Spam is spam, and should be 
caught by rules, etc regardless of the time it arrives. Ham is the same also 
regardless of it's arrival time. A good set of rules should work fine any 
time of the day. The percentages only indicate when people are sending mail, 
so this is a useless figure for comparing day/night averages.

For instance, if the same message that came in at night were resent during 
the day, how should the mail be treated? Different score and action?
