I agree that the GCM distance comes to 41K miles. I understand that the land segments are ok with RWSTAR routes, but the land segment mileage still must be included as if you had flown the route between the two points. I found this:

Surface sector - the last point of arrival & the first point of departure together count as 1 stopover.
Mileage for surface sectors must be included in the MPM calculation.
If a surface sector attracts more than 1 TPM, the lower applies
