@Godisme: The limit is 5000. You can't go past that limit. And as I said, older entries are periodically cleared from the database. RC data is pulled from a special table, not from the revision (history) table.

Also, the first edit doesn't necessary shows who was the founder, since I can see several new wikis where the founder never edited. Someone else could start editing a wiki. RC is not reliable for that.
