Question about "institutional priorities" and chances/acceptances

What I find amazing is that many participants on this thread seem to have missed the OP’s point, which was that, in some cases, colleges’ “institutional priorities” might make admissions outcomes less correlated than would generally be expected. The OP used the example of the proverbial oboist and I ran with the idea in post #10, but most of the other commentary has strayed from the OP’s actual question.
