After seeing the
points charts I see that much of the basis of my question was incorrect as it was coming from the poster that seemed to say they had purchased a week 52 for 139 points and that the fixed weeks were discounted. I must have misunderstood what week they purchased.
So it seemed obvious in my head from that info to at least purchase a week 52 or some other discounted week if it was ever possible you might use it since you can cancel the week without any penalty at all. But I'm still surprised at the pricing and lack of "penalty" - ie you get points one for one if you cancel the week - so it still might make the most sense for a particular buyer who often visits in a popular week even if they thought they'd only go that specific week every 3-6 years and would cancel it for other times or resorts in other years. Or even more so for a new buyer with contract minimums although that brings up another question of what DVC will require from a new buyer if they want to purchase a week in a studio that would be 139 points but the minimum is 160? One of the lessons learned from the 2 years of point reallocations, and in a small part to the point change made at BLT prior to opening, a cushion can be a good thing and in the meantime they could work the fixed week nicely by using it in high cost years and cancelling and booking with points in other years when they want to go at other times. As I understand it Aulani's fixed week have what sounds like a true 10% upcharge and you don't have the 10% extra points to use when you cancel a week. The VGF only has a premium price if, as you mentioned, a person only ever used it for the week the purchased.
Overall it seems like DVC is missing an opportunity to maximize profits with this pricing model on the fixed weeks and by taking up to 35% of the rooms out of the pool at the most popular times (as I assume those are the ones that will sell the fixed weeks) the remainder of the VGF purchasers are losing as well with less availability.
