As for UChicago’s underlying reason for the rapid rise, I think you and I agree that it should be in the top 10 (and probably top 5). How it went from USNWR #15 to #3 in just 12 years is a separate issue. When you change admissions policies to help with selectivity and rankings, that’s playing to the rankings.
