The number of savvy add-on owners looking to break contracts up into small bits is almost certainly in the noise.
It's not just the savvy owners who split up their contract, rather there are also current owners who:
1) Wish to add a small piece of the latest-and-greatest to their portfolio, and
2) Have made incremental add-ons following an initial purchase.
The former group consists of current members who are not breaking up contracts, rather they are simply buying 50 or 75 or 100 points for short stays or use every 2-3 years. I don't see that as a practical approach for Aulani.
The latter group consists of owners who bought AKV or BLT dating back to 2007, and have since decided to add-on in small amounts. Perhaps in response to the point reallocations. Perhaps due to incentives offered since the initial purchase. Perhaps because they wish to vacation more frequently.
Ultimately, I would propose that the Aulani population lacks all 3 elements which typically produce small contract sales: desire to split larger contracts, sub 160-point add-ons from legacy owners and sub 160-point add-ons from Aulani owners.
