The two things that ought to matter most here are (a) the inherent quality of matriculated students,and (b) their suitability to the University of Chicago. I take test scores and gpa (pace @DeepBlue86 ) as rough proxies for (a) and numbers admitted ED as rough proxies for (b). We don’t yet have the stats on this year’s admitted class in support of (a), but if those numbers are, as I believe they will be, at least as good as the ones for HYP, and if the numbers admitted via (b) are higher than ever - well, in my mind, the case is made that Chicago Admissions has found the right kids for the right school, which is all we should care about.
