I don't know if this helps or not, but I know someone who got off the ND waitlist (I believe it was in either May or June) 2 years ago with a 165/2.9-3.0 (can't remember the exact GPA). Said applicant told me they were ask to provide additional information, applicant emailed them a 1 page continued letter of interest, and 2 days later they were offered a spot in the class. She's now a 2L and on one of ND's journals. I got to visit her in July of last year, and she said she's happy with her decision to attend.
(. . .for what it's worth)
