Hey, I’ll tell you what – you don’t tell me when to stop posting, and I won’t tell you.
The reason these mathematical concepts have been covered in this thread is that others have made incorrect statements about them, and I (and others) have been trying to clear that up.
Besides, I wasn’t the one that brought up the idea of mathematical modeling. Basic mathematical concepts still apply, even if you aren’t doing modeling. Why is that so difficult to grasp?
Further, everything you state can be modeled mathematically. You just have to use more sophisticated techniques. And you don’t have to get 100% accuracy for it to be useful.
Decisions may not be based on stats alone, but I guarantee you, at every school in the country, the chances of getting in are higher if your stats are higher. So even modeling based primarily on stats will be somewhat accurate. Naviance is quite popular and successful, I understand. (And as they get more data, they can do more sophisticated modeling.)
And in fact, I’m sure there are many out there that are doing very sophisticated mathematical modeling of the college application process, to their own (and others’) enrichment. It’s even being done by schools – why do you think it’s now being called “Enrollment Management”, not just “Admissions”?
