Good points on the previous entry, old chap.
I would almost want to suggest a separate, but almost equal "Territorial Points" system. They would / could perhaps count as a 'bonus' to the motherland, or 1/2 point, or just a Territorial Point.

So, in practice, we could file various ambiguous locations under this system, and they would be recognized as such.

A Territory could be a place that is a) geographically far from the 'Mainland', and/or b) culturally rather different. Thus even the Åland Islands could be counted as a Finnish Territory Point for, say, an American gentleman visiting. Likeways Guam, or Puerto Rico, would be bonuses 'added' to one's U.S. point...

What say ye?

Ta ta!
