The two programs I emailed about second looks never got back to me. Later I found out from one of our very reputable faculty that it's pretty rare to do "second looks"...the logic is that, for one, it's kinda late, for two, the end results don't change that much--at this time what's done is usually done, or almost done. And based on what I've seen from other specialties from the last class, these points seemed to be true.
Also, he said "if you're going to look (interview) a program for the second time, don't you think it's only fair for THEM to look (interview) YOU for a Second time?"

Harsh as it may sound, there's some truth in that.
So, I decided to keep quiet about any second looks. What's done is done, I seriously doubt second looks can drastically change any selection committee's already formed opinion. I suppose the only good is help you make a more informed ranking list....although there's also this thing called "too much information"....
