This^ Ned, you are spot-on. The frustums, having been generated solely based on aesthetic desires rather than being a natural response to the program or necessarily the structural needs of a supertall, wreaked havoc on the floor plans as we have previously discussed in this thread...

Even with the current dimensions, the condos had to be planned taking out a whopping 4 1/2' along the entire perimeter from the largest to smallest floor plans... they arguably don't work now, I can't imagine how they worked taking out 10' along the entire perimeter instead of 'just' 4 1/2'... they probably had to change the condo floor plans and room counts forcing shifting back and forth the locations of plumbing risers which just added to costs...
