It's probably worth noting the Eric happened to have revised
SpamCopURI recently also, to version 0.21.  Perhaps more
importantly several people have tried SpamCopURI 0.21 with
SpamAssassin 2.64 and they seem to work just fine together.

Thanks for the additional stats.  I'll assume the spam detection
rates for AB and SC are probably low because Daniel's spam corpus
covers a much longer historical time period than would typically
be encountered with messages in real time.  Other rule stats
seems to suggest SC, WS, and OB have fairly similar spam
detection rates, such as these from Raymond Dijkxhoorn:
