@Postmodern, That’s very interesting – I never would have guessed that EA gave a student such a significant advantage. Does the book only address tippy-top schools or do they mention if the same advantage holds at more average schools? (I can guarantee my D isn’t getting into Harvard however early she applies!)
^^^^ @snoozn , the focus of the book is on elite schools as that where they got the data from. I’ll pull it off the shelf and check for exactly what schools later if I can.

Apologies, as this is not entirely related to OPs initial question, but I found it informative.
