I dont entirely agree with you. If they read an interesting personal essay along with unique secondary essay answers, your personality can shine through tremendously. Yes numbers matter, but only to an extent. I think the essay portions of the application are, by some, totally blown off which I think is a big mistake. I tried my make my total application as unique as I could fully explaining:
1. All my AMCAS activities and my personal take on them.
2. Explaining my choice of medicine with a unique personal statement.
3. Writing creative answers to the conventional questions. Just tried to be non-linear in my essay writing. I know they read hundreds a day and it is like a breath of fresh air for some if they read something creative and interesting.
Later.
