See http://en.wikipedia.org/wiki/Special:ArticleFeedbackv5/Common_snapping_turtle for example; only one of the posts, evidently, is being counted.
<tl;dr> Calculation of numbers is pretty intransparent currently. Long version: http://en.wikipedia.org/wiki/Special:ArticleFeedbackv5/Common_snapping_turtle right now states * 47 posts about this page * 34% found what they were looking for Clicking "All comments (41)", in the list there are: * 12x "found what they were looking for" * 29x "did not find what they were looking for" It's pretty unclear how these 34% are calculated, likely because 6 posts about this page are not displayed (as they are empty?). 100 / 41 * 12 is only 29%, but assuming that some of the 6 hidden posts are positive, 100 / 47 * (12+6) is 38% so it's likely somewhere in that range.
