I'm not sure what you're asking. Is this about "validating" bookings
against a member's points? That's done by the scheduling website. If I
tried to book more than my "budget" permitted, it would be denied.

correctly, no one will care how much the plane is flying unless they
want it at the same time.

The point system exists not for cost allocation, but - as you note - for
managing availability.
