Approximately when are fall PointSavers loaded into the system?

I am looking at a property (R.I. Minneapolis at the Depot) that appears on both the Spring and Summer PointSavers list. I want to stay there 3 days after the Summer PointSaver ends. What are the chances that it will appear as a fall PointSaver?

(As a PointSaver, I would do an award stay. As a non-PointSaver, I will just stay at the weekend rate.)
