We've owned SSR since 2009. We always travel in either early-mid July (but always after the 4th) or early June. We always book a 1 BR for our family of 4 (me, DW, DD22, and DD19). So far, every year when I checked, at 7 months (on the dot), both AKV Standard View and Boardwalk Standard View have been available. We've also booked BLT Standard View twice - both times it was not available at 7 months (we booked Boardwalk at that time) , but we did get in via Wait List (we always book 8 to 10 nights and never want to split stays and change resorts during the trip, so the whole 9 nights had to open up to get into BLT). We are not at all picky about theming, and never spend much time at the pool. Our goal is to save money on hotels so that's why we always look for Standard View rooms, so we can maximize the number of nights we get for our yearly trip.
This has worked well for us, but as many others have said, if you absolutely must stay at Boardwalk or BCV or BLT (or wherever), and you can book at 8 to 11 months, then buy there. And if you are never going to book earlier than 7 months, then points is points, and there is no advantage to owning one resort over another
