I've seen this before, and I think it's ridiculous to assume that there's some arbitrary cutoff about top 10 colleges. Why is not percentile based?

For reference, there's 12 Houses at Harvard. With a bit of paperwork, they could each be a separate college, pushing Dartmouth all the way down completely out of the top 20. But would the education at Dartmouth have gotten worse in any way?

Rephrased, what if we instead classify the Ivy League as a single college with eight campuses? What's the difference?
