Through my involvement in the thread getting the original 2020 point charts overturned and many calls with DVC management, I just want to clarify a few points.
Technically
@spencercl is correct the total number of points has never changed at a resort, because DVC is only contractually obligated to consider the total number of points to book a resort as if all lockoffs are booked as 2 bedrooms. This leads to the point you are making (and the contract for VGF actually outlines) which is the lockoff premium. Essentially DVC has said that the points to book at 1 bedroom and studio could be more than the point costs to book a 2 bedroom lockoff.
So in a resort without any dedicated studios and/or 1 bedrooms (VGF, SSR, etc) they feel they can increase studios and 1 bedrooms year over year without any decrease anywhere else because the total number of points to book the entire resort hasn't changed from the legal requirements. I specifically asked could the points required for a studio at VGF increase 20% each year (the limit it is allowed in the POS) indefinitely and they said yes, but would never do so because it wouldn't be in the best interest. Some of us on the other thread took them to task on many points specifically that increasing the lockoff premium wasn't in the best interest of the members and/or that they can't reallocate points across room types. DVC hasn't admitted any wrong doing and denied any points people brought up but simply reverted the change "due to member feedback".
Also VGF's POS does specifically state that points for the 1 bed and studio can increase without corresponding decrease because they are all apart of the lockoff. They also stated promotional material isn't legally binding, for example the DVD referenced above as promotional material which wasn't meant to outline every point of the POS (same with the Product Understanding Checklists) but only meant to give a broad understanding. Again many of us took them to task on this as a change in DVC's reading of the POS as these items weren't really an issue before.
