A contract with December 2025 points is still stripped because December 2025 points can't be used yet.
Regardless, dues and points don't actually have anything to do with one another as dues are tied to calendar year, not use year. I know it's a heuristic in the resale community to pretend like the burden of dues should be borne by whichever party gets that year's points, but that's not actually how the dues are structured.
2025 dues are for January 1, 2025 to December 31, 2025. 2025 points are for December 1, 2025 to November 30, 2026.
