This is from the statistics for "4 June 2005" from the URL above:

   13219 sbl-xbl.spamhaus.org (union of all results)
   10757 cbl.abuseat.org

Even if those are absolute numbers, and do not include false positives,
they allow us to say things like "most of the spam caught by SBL-XBL
comes from the fact that it includes the CBL". which is what I meant.
