Thanks, Roan, Hercule, Brad, and Alex for your helpful responses. To summarize, the following factors complicate my simple picture of how registration and editcount work:
1) usercontribs includes more events than recorded in editcount (such as renaming a page) 2) there may be history imports that bring in edits before the registration (or after) the registration date 3) sometimes user accounts are recreated even when they have been renamed. 4) there is a bug in which "users with large edit counts don't get re-attributed properly in the revision table" https://bugzilla.wikimedia.org/show_bug.cgi?id=17313 -Raymond On 12/14/10 1:31 PM, Brad Jorsch wrote: > On Tue, Dec 14, 2010 at 08:22:15AM +0100, Hercule wrote: >> Editcount register the edits made by a user.
