Does it really? That’s kind of odd. Your suggested query doesn’t really give me an easy way to evaluate the difference, although maybe I’m not using it as you intended.
In any case though, thanks for looking into it, but I think it’s really unlikely that’s the issue. The set of counts and users between the query and the summary page are literally identical (and occupy a fairly wide range, they don’t differ by one or two likes), the counts are just attributed to different users on the summary page. The counts on the summary page don’t align well with my experience on the forum, either.
