SURBL is looking for statistics about what portion of unsolicited our lists are detecting (ideally in large mail flows). An overall number would be ideal, as in what fraction of total unsolicited messages are caught by any SURBL list. One possible way to measure this from SpamAssassin-processed messages would be to count the messages marked as spam that had 'SURBL' in their scores versus the ones that didn't have a SURBL rule hit. The ratio would be the spams with SURBL hits divided by total number of spams.

I should have added, here is a SpamAssassin meta rule that may show how many messages hit any surbl rule:

meta URIBL_META_SURBL_ANY (URIBL_AB_SURBL || \ URIBL_JP_SURBL || URIBL_OB_SURBL || URIBL_PH_SURBL || \ URIBL_SC_SURBL || URIBL_WS_SURBL) score URIBL_META_SURBL_ANY 0.01

(For however the line wraps should be handled.)
