From 11 months to 7 months plus one day from check in, only home resort points can be used to book a resort. You don't even have to own there. You could have BCV points transferred into your account and book BCV 11 months out using those transferred points. So it's not being an owner at resort XYZ that allows you to book there 11 months out, what matters is having enough XYZ points in your account to pay for the reservation you want to book.
At 7 months from check in you can book any resort using any points.
