total pts at the resort cannot change but that is determined using the number of villas times the pts required.
for example, if i have:
100 standard villas at 10 pts/nt (100 x 10 = 1000) and
100 preferred villas at 15 pts/nt (100 x 15 = 1500)
that would mean the resort total was 1000+1500=2500 pts
if i moved 20 villas to the standard category that would now use up
120 standard villas at 10 pts/nt = (120 x 10) 1200 pts...
so allocating the remaining 1300 pts (2500 for the total resort less 1200 for stnd villas) over the 80 preferred villas would push the requirement up to over 16 pts per nt.
that's just an example using 1 night - the actual calculation would be several different villa types over 365 days with different seasonal costs per night.
