My dates fall into the 35% range, which is what I already booked with the public offer. However, there's no availability at the resort I booked anyway, so I'm happy to leave well enough alone. I really wasn't expecting a big AP discount anyway - they seem to be running very close to the public offers lately.
As to why the Poly would show rack rate, since the Poly shows on the list, I would guess that the rooms they set aside for the promotion have all been booked. They do limit the number of rooms they will discount at each resort, and with some rooms removed from inventory at Poly for the DVC project, they may not need additional discounts to fill the resort. They may also be using the discounts to encourage people to book resorts other than Poly by offering fewer rooms, so they don't have as many guest issues during their refurbishment. It could only be one night that is sold out at the discount rate, so you might want to play around with dates and see if the discount comes up for at least part of your trip.
