Even ED may be pretty idiosyncratic, depending on the school, however. For instance, looking through the Cornell ED thread in the past, you saw some non-hooked kids with worse stats get admitted over non-hooked kids with better stats. Evidently, profs sit in at Cornell, however, so they may be looking for potential, not scores.
Still, if your goal is “some Ivy/equivalent” or even near-Ivy, ED to one of Dartmouth/Cornell/Northwestern/Williams/Amherst/JHU/Tufts (or EA to ND&BC) makes a lot of sense. Each has a early acceptance rate above 25% and I’m hard-pressed to think of anywhere that you can get to from other Ivies/equivalents that you can’t from those schools.
