I just voted to close this question over on physics and I'm confused with the result.
When I was shown the question in the review queue, it had four close votes as off-topic, but I disagreed with that assessment - the way I see it, the question is a clear duplicate of this other question, and they both share a tag in which I have a gold tag badge, so my close vote should work as a dupehammer and singlehandedly make the question a duplicate.
However, after voting to close as a duplicate, the question got closed as off-topic. Now, if my closevote was a regular-3k+-user vote, this would be the expected response, since the question has five close votes and the majority reason should win out. However, if my vote had been outnumbered by three-to-one, it would still be able to override the off-topic votes and close as a dupe, which is a bit less harsh on the OP and more useful both for OP and future visitors. Is the step from three-to-one to four-to-one outnumbering that meaningful?
Or, put another way, even if it's an outnumbered last vote, shouldn't a dupehammer override the existing reasons and close as a duplicate?
