Carrigan/Wagner is a red herring that should have been removed from the lists already. 207 is the number for the T207 master set.
However, I don't see why a given collector couldn't call his or her set complete at 200. I would argue for a distinction between a "set," which I see as a nice broad term that could be defined a lot of different ways by different individuals, and a "master set," which should be used more strictly to designate every known variation.
For me, I don't care that much about tiny variations-- I care about poses. I got copies of both Mullins, Austins, three Livingstons, etc., because it was easy enough to do, but generally if I have all the poses in a set, I'm going to consider it complete for me. If I ever get one Irv Lewis 
, I suspect I won't be worried much about getting a second one.
