Other than ppl that have been around since before the node counting code got straightened out (and NodeReaper who experienced a separate bug), the only reason I've seen for write-up counts to be off is that Categorized Questions and Categorized Answers are counted but don't show in your list of write-ups (because they end up being owned by QandAEditors for convoluted historical reasons).
