Thank you for linking to that bug, Marcel. Just
to verify what you are
saying, would it be right to say that the bug fix caused a a lot of
pageviews to be moved from the respective (nonexistent) pages to "-"
pageviews? And, does that means that the current estimate of "-" pageviews
is more accurate than it used to be prior to the bug fix?

Maybe the high value in October (45M) has
something to do with the last
changes in
https://phabricator.wikimedia.org/T145922 ?
