A returning theme on our beautiful and productive Meta sites is the topic on downvoting without leaving a comment. Yes, that is a bit cheeky and admit it: you've done that as well.
In a recent post it was claimed that 90% of the downvotes weren't accompanied by a comment. That percentage seemed rather high.
Given we have some public statics in the Data Explorer, how many posts (count / percentage) are there that received a downvote, but no comment? Per site would be a good start, but if any one fancies a network-wide query I'll be super excited.
I realize the downvoter and the commentor might not be the same user, but the user that claimed that 90% figure had that same restriction so for now it is safe to ignore that point.
If a CM can run one of the queries in the answers to come on their private SEDE instance to include stats over deleted posts, it would be awesome.
I've found one question that is related, but its scope is rather narrow for the purpose of this question.
