Of course, playing with the dates just a bit, very clear that owning would provide much more flexibility with respect to which dates are available. Plenty of dates just don't show any availability for the heavily discounted rates. And, it does seem like these heavy discounts are primarily targeted at the summer timeframe which, well, I'm not opposed to a summer trip to WDW, but it is a bit like living on the surface of the sun for a few days

. TBH, I think some of this really argues in favor of points chart adjustments. Summer should be less points. December should be more, especially early December. That would probably go a long ways to addressing some of the issues with spec renting too.
