@AWC: You'll find that a lot of the imported articles on the City Building Games wiki I linked in my initial comment contain several edits by myself.

@Ripto22475: Special:Editcount registers all edits, regardless of the source. When importing content, it automatically recognises those edits I've made, hence why it is accurate to every edit I have made. Yet the masthead just reports "actual edits" and completely ignores imported edits, which makes no sense and seems flawed. It should be noted that the wiki I imported the content from wasn't actually closed: I simply took a copy of the source wiki because I felt the administration of the source wiki was terrible, so I wanted to make a better wiki where people can actually contribute and not be treated like vandals for improving articles in a good faith manner. Since I had contributed heavily to the source wiki (before being erroneously blocked), I didn't want to have to start over with the content I'd already contributed.

@452: I'm not sure. The stat on my userpage updates whenever the cache of the userpage updates, so is a bit delayed from what it should be reporting. I believe Special:Editcount updates immediately when you make an edit (locally), but I'd assume the "All Wiki's" section would be cached to update once a day. My suspicion is that, because I only started editing CBG Wiki recently (about 20th February or something), the masthead only counts the edits made from my join date and ignores all the edits that were imported, as they were made before my first edit to CBG Wiki, but that's not much of a reason: like you said, edit count reporting should be uniform everywhere, not disjointed.
