Hello,
many people on plwiki have pointed out (discussion) that the statistics on Special:ValidationStatistics are not up-to-date. The main issues are with the areas marked "2", "3" and "4" on the attached (below). These figures have hardly changed over the course of years, as can be observed by comparing archived versions of this page (IX 2015, XI 2018, 03 I 2020). There's probably a bug somewhere in the function getEditReviewTimes() (github). As we are in the midst of pretty extensive discussion of the flagged revisions, many people would love these statistics to be updated more frequently (once every couple of hours instead of once every couple of days as it is now).
Thanks in advance
