I'm not comfortable sharing my profile in public, but if you PM me, I'll share it with you!
I've been told that admissions can be extremely unpredictable. There are applicants with no research experience who get into the top programs, or vice versa, applicants with excellent profiles who are rejected. Sometimes, programs reject students not because their profiles are not strong, but because their POI is leaving, or they just decided not to take in any students that year, or there was a lack of research fit, etc...The advice given to me was to apply to as many schools as I could afford to, and not to pin my hopes up on any specific school, just because so many factors can affect admissions. Though I believe that a strong GRE/GMAT score is extremely important for making the first cut, especially at the Ivy Leagues.
I, too, have a backup plan. I'll likely work for 1-2 years, gain more research experience, then try applying again.
