We have stayed in our home resort about 60% of the time...so no option there for that kind of pattern. Mostly we wanted to stay in every DVC resort at WDW (we have, except for Poly) so that's why the number is so low for home resort bookings.
gotcha, I guess my intention in the 2nd choice was to find out how many have bought cheaper points only to stay in other DVC resorts, while choice 3 picks up those that have stayed in multiple DVC resorts

Own BCV and have also stayed at multiple resorts. Just got back yesterday from a split including BWV. Because my heart is so loyal to BCV as my 'Epcot resort', I was surprised how much I loved BWV and now 'get it' why so many think BWV is such a pleasure to own with very reasonable points.We mostly stay at BWV. Lots of times we end up staying at multiple resorts so have stayed at BLT, OKW, SSR, AKV, BCV, VGF and will be staying at the POLY on our next trip.
. I have had so many opportunities to do so many amazing things with our ownership in such a short amount of time. We have stayed at aulani, vgf, bwv, vwl, and I just booked Easter at akl, bwv (the family loved it!!) and ending at vgf. I could see us buying more points resale at bwv to use for there and anywhere else we want to stay.
