I'm curious about how well I judge worthy questions in comparison to the rest of the community. How can I get a count of how many questions I have voted to close or delete, and how many of those questions have stayed closed/deleted vs. those that have been reversed? Am I an active closer compared to eligible users at large? (Probably, simply because I close at least a few every day and am aware enough to ask the question.)
Questions that have been reopened do not show that they have been closed, unless I try to close it again and I'm informed that I cannot vote to close again. It would appear that a question timeline doesn't display a close event, let alone a re-open event. My understanding is that questions that have been closed and then re-opened are not shown as such in the data dump, either.
