That says that in the 10.5 hours starting from 9:30 am until about 8 pm,
my server has received 1056 reports of the checksums of messages. 
Of those, 385 or 36% look like spam because they have addressee counts
above 10.  (10 is a reasonable threshold for my vanity domain, and
for the other clients of my DCC server, all of which seem similar.)
Assuming that a substantial fraction of the remaing 64% were not spam
implies a much better than 25% effectiveness against the spam seen
around here.
