Maybe it would make sense to actually label Live edits and Deleted edits as something like Edits to currently existing pages and Edits to no longer existing pages? "Live edits" implies that the edits are still present in current page versions, which is obviously not guaranteed even if they haven't been directly reverted; and "deleted edits" implies that the edits themselves were deleted. I doubt most people interested in user stats would bother coming to XTools/Edit Counter to read about the clarified meaning, they're just going to make assumptions, and a disruptive user with most of their edits reverted is going to look better to them than a page patroller.

I think we can add little help icons (?) that explain this, sure.
Right, that would work as well, thanks.
