Maybe, maybe not. Although I don't have any definitive proof, I have long suspected that
DVC sometimes projects availability based on future declarations, not just what is declared on the date the reservation is booked. For example, as of today DVD has declared 40.71% of the Polynesian Villas & Bungalows for the DVC inventory, which means that DVC bookings using points are limited to booking no more than 40.71% of the resort. However, DVC may know that DVD will do another declaration by October 1, 2015, that will raise the DVC percentage to 75%. Its possible DVC is already permitting members to book 75% of PVB for all reservations commencing October 1 or later. If that is how DVC operates, then there wouldn't be any "new" inventory immediately available right after another declaration is made.
My suspicions are based on some observations when DVD was making declarations for AKV. A handful of people posted that their AKV waitlists did not come through immediately after more AKV inventory was declared. Also, there were a couple declarations made for AKV that didn't seem necessary. DVD had a large number of declared-but-unsold AKV points in its inventory but it still went ahead and declared more points for the DVC.
I know, not overwhelmingly strong evidence to support my suspicions. That is why I said "Maybe, maybe not."
