Okay, but still. You explained why the yield is not 100%, but not why it's 50%. I'm just going by what was reported last year in the NYU thread.
They initially issued exactly one A for every seat in the class, and I think it was reported that they went around 50 deep in the WL. This makes sense if the yield is around 65%, which seems reasonable given that NYU is T10, not T20, and that everyone receives full tuition with select people receiving more. How many of those people are receiving comparable packages at comparable schools, and how many people actually prefer NYU even with a comparable package elsewhere? USNWR data could be dated, as I'm sure the yield was much lower prior to 2018.
