For what it’s worth, last year my child applied RD and was waitlisted. ED will make a difference in the strength of your app. My kid’s stats were as follows: double legacy (parent and grandparent), ACT 35, GPA 3.7, campus visit, early app for scholarship consideration. ECs were not textbook spectacular but coalesced in a unique and compelling narrative. Waitlisted. Ended up going to a different T20.
