How can edits from logged-in users be down 152%?  The maximum decrease
should be 100% - and that would mean no edits from logged-in users.  Same
for first edits by logged-in users.

I seriously wonder about the number of "accounts" created on mobile - are
we really adding 0.05% of all of the current existing accounts every single
month just on mobile?  Or does that include accounts that already existed
on a WMF site?
