I don't know how you can ignore purchase price per point. That is such a big part of the equation. Yes after you have outlaid the cash upfront it comes down to the
point charts and the dues.
Also if making these examples and paying the points why are you not showing examples using the home resort advantage?
All of your examples are using the dues of that said resort.
Your examples really should be the dues of your resort (BLT $8.02) multiplied by the cost of the room you would more likely to grab at 7 months or if your an owner the rooms that you have the first chance at grabbing.
As a BLT owner I'm not grabbing a Lake view that has quite the supply and instead would be grabbing a standard 1 br for 226 and costing $1,812.52 or a theme park for 305 costing $2,446.61
For Riviera use your BLT to stay at the preferred 1 BR meaning $8.02 x 328 = $2,630.56 but if I am an owner I'm taking advantage of the cheaper room so I would take my dues of $9.06 and multiply by the standard 1 BR of 259 costing $2,346.54
Likewise for AKL your BLT dues for a savannah 1 BR come out to $1,884.70 but as an owner there is a chance for a value 1 BR at $9.64 x 144 points which ends up costing $1,388.16
