Did someone ever make a synthetic view of the stats for https://meta.wikimedia.org/wiki/Flagged_Revisions#Flagged_Revisions_on_Wikimedia_projects, ideally graphed over time? Cf. https://bugzilla.wikimedia.org/show_bug.cgi?id=42360

To show what I mean: there are several wikis where around 20 % or more pages under FlaggedRevs are out of date, with edits waiting on average for hundreds days (and sometimes years). (There are also some wikis where the average is above 1000 days, but for few pages.) https://sq.wikipedia.org/wiki/Speciale:ValidationStatistics https://ru.wikipedia.org/wiki/Speciale:ValidationStatistics https://uk.wiktionary.org/wiki/Speciale:ValidationStatistics https://sr.wikinews.org/wiki/Speciale:ValidationStatistics https://de.wikiquote.org/wiki/Spezial:Sichtungsstatistik https://ru.wikiquote.org/wiki/Speciale:ValidationStatistics

There are few wiki characteristics/stats showing a greater variance, so an interesting picture can be producted just by organising existing extension data scattered across wikis.
