Recently I discovered that the user_editcount column in the "user" table
disagrees with the actual edits in the "revisions" table by a significant
amount. To fix this, I ran maintenance/initEditCount.php. My question is: what causes
these numbers to get out of sync in the first place? Should I need to run this
maintenance script regularly?
This is MediaWiki 1.16.2 on a single server with a single database. The wiki began its
life at 1.10.0, if that matters.
