Yeah, there’s a bit more pressure on grades and scores because, as my friend and great track coach once said to me, “Smart kids run track.”
I would caution that although those guidelines will work for all, some are a bit more flexible than others.
And yes you’re spot on that some NESCAC coaches go to NIN, NON, NBNI, NBNO, AAU or USATF Nationals, but not many. Those would be good opportunities to try and engage and get a sense of what the grade and test hurdles are. Problem is, those are hard to qualify for after Freshman (tough standards for Championship in New Balance and even Emerging Elite at Nike).
This my point about OP making all-Conference Sophomore year and posting good distances in the summer as an entree to coach outreach either that summer or fall Junior year.
They can’t recruit you but I’ve observed them giving guidance on target test scores indirectly. The earlier you know, the better; not that OP needs any additional incentive
