There is no "skim". The value given to each owner each use period reflects the total number of points in the season they own - which has some weeks worth more in absolute terms than others but all are in that season - divided by the total number of weeks and the resulting average value is what you get as an owner. No skim.
Lets do it very simply.
There are 4 Golden weeks. There are 100 total owners. But one is a holiday week. So 3 of the weeks cost 500 points to reserve but the one holiday week costs 700. The total available points to all owners of that season is 220,000. But no one "owns" the super value week - all owners can try to get it - so the value each owner gets is 550. No skim. No one gets the value of the super week on total and no one gets only the lower value. They all get their fair share to use as they please.
If there were deeded use weeks then each of the 3 should get 500 points and the owners of the 4, super week, would get 700. But they all have a right to it & all get the value. Get it?
