Ask PG: Downvote-related statistics?

With the recent talk about downvotes and karma threshold, I have become curious about my own downvoting pattern. Subjectively, I think I upvote far more often than I downvote. Subjectively, I think I either dispute a comment in a reply or downvote it but rarely if ever both. No urgency, but the next time the list of things to consider needs a fresh injection of ideas, please consider ways of measuring people's downvote behaviour and providing some feedback. It would be very interesting to see what we users do with our downvoting power. It couldbe something as simple as a ratio between upvotes and downvotes. It could be something weird like counting how often you downvote something AND respond to it. I don't know what form the feature should take, but it would be interesting to be able to go into my profile and get some feedback about my own behaviour when it comes to downvoting.
