DCC Graphs

Hi, 
 
I would just like to confirm what the means of the Gprints are on some of
the graphs,
like for instance the mail check graphed.
 
Total mail: is the avarage amount of mail that comes through my mail server.
Likely spam: is mail that might be spam.
Trapped spam: is mail that is confirmed spam.

And the above are not graphs of what have actually been blocked?

Thanks,
Ilo Lorusso.
