Some ideas (some may be a duplicate from your list):

- number of all message signed by this milter
- number of all messages checked for signatures
- number of messages containing any signature (valid or not)
- number of messages containing a valid author domain signature
- number of messages containing a valid third-party signature
- number of messages coming from a mailing list containing
  any signature but not any valid signature
- number of messages NOT coming from a mailing list containing
  any signature but not any valid signature

Distinguishing broken signatures in direct mail vs mailing list
mail provides much better indication of the quality of signatures.
A mailing list recognition may be just a good estimate,
like checking for presence of any of:
  Precedence: list
  List-Id:...
  List-Post:...
  List-Unsubscribe:...
  Mailing-List:...
  From matching /^...@]+-(request|bounces|owner)/ or /^owner-...@]+/
