Also, if you are looking on the cash booking site, Disney only own about 2% of the DVC resorts, with the exception of the Poly, where they own ~30%. Any other rooms released to Cash Rez occur due to member banking, trade out, or other alternate point use.
November and December are the highest demand months for DVC members to book with their points. I wouldn't expect a lot of trade-outs to Cash Rez in November.
