I know for May of this year, I booked on the morning of the 11 month mark and got the last one available with points for only 4 nights, could not get a full week. Someone else on here went on the waitlist at 7 months for May and it never came through.
All you can do is hope for pixie dust. Maybe you could do a split stay; I think your chances of getting a full week at the 7 month mark might be ambitious.
