The individual project listings seem to be incomplete, e.g.
https://stats.wikimedia.org/#/en.wikipedia.org/contributing/top-editors/normal|table|last-month|~total|monthly
doesn't match any of the details in
https://en.wikipedia.org/wiki/Wikipedia:List_of_Wikipedians_by_number_of_edits#1%E2%80%931000
(updated daily by bot)
The main list when we click from "root page" to "Contributions" to "Top Editors" also seems to be incomplete
