I noticed your posts on the Rent/Trade board. You need to start farther out as Granny mentioned. Also I noticed you are mostly asking for 1 night only. That's just not worth it for most owners to go through the hassle unless they have a previous reservation that they have to get rid of. If they did, it would be unlikely to be for one night only.
If you really want BCV for October you probably should look for a standing reservation that is being sold - might even offer a bit more per point as those reservations are likely at a premium for that time of year. Otherwise, start requesting at 11 months out for your NEXT trip - that would give you a better chance of success at BCV.
