I have no intention of getting into a semantics argument with you. If you truly did get a 36 on your ACT, then you know what I am talking about. All of the schools you listed are great institutions. But yes, a 32 or 33 on the ACT is nowhere near 35. And Northwestern doesn't have a team, so let that one go. In general, if you are an elite academic student and a good runner, you are most likely looking at the Ivies, Stanford, Duke, Vanderbilt, Rice, and possibly a few others. The west coast folks will consider the Cali schools which are all very competitive as well, but don't hold the national prestige levels of the others on this list. And I will still argue that while the Ivies are Div 1, they really don't act like they are in terms of recruiting, and after Harvard and Princeton, their programs are really not at a D1 level.
My original post was about the lack of options for good runners (sub 9) who are also elite students who want to go to one of the top academic schools. You really only have the Ivies which are all NE, and Stanford in California and Duke in Carolina. Its not a lot of diversity of schools, location, type of education, etc.
D3 on the other hand offers more top tier colleges. Not in terms of number of students but rather the number of schools and their diversity. Hopkins and Tufts are very different schools than MIT and Caltech. Just as Wash U in St Louis is a completely different experience than Pomona in California. I know you don't believe it, but there are certain sub 9 runners who view academics as their primary focus, and have the financial means to not make their choices solely on cost. It is not a large amount, but they do exist, and in those cases, they may choose a D3 over a D1 based solely on the type of school and not because they couldn't cut it at the D1 level.
