The fundamental issue is that crushing the SAT/ACT is more of a reflection of “mom and dad got me good tutoring or prep” than it is intellectual merit.

I “weaseled” my way into CMU via athletic admissions (I was an actual athlete, not a Lori Laughlin style one), but did very well at CMU once I got there. People who aced the SATs did not do as well. Fwiw I still did okay, 32 ACT score, but there were 35/36’s around.

IOW, prediction of academic success is hard; career success harder. These standardized tests don’t add much.
