It does not appear that a resort's points are equally distributed among the 8 UYs. For example, at BWV the most common UY is December with 19.46% of BWV's points, while September is the least common UY with 7.83%. At VWL, August has 23.72% of that resort's points, while the March UY has only 6.17% of VWL's points.
BLT's UYs are even more unbalanced with February being the most dominant UY. About 26% of BLT's points is still to be declared, but even all of those points are placed in the other UYs, February will still end up with about 34.4% of all of BLT's points.
