I'm torn about the way they handle this; I'd prefer a ranked list so I would know my chances and could, for instance, pull the trigger on AMCAS 2011 right now if I had a low ranking. However, I do appreciate that they actually take the time to sit down and review the files again, giving us an opportunity to update and improve them. I'm hoping my LOI and fresh LOR will give me a boost. I also wonder if MI residency is considered. One thing I would especially like to know is when the committee meets, so I would not be so obsessive about checking my email. But, as you said, it's all a mystery! I got a good sign today; This is a maize and blue household, but we randomly received a package from my slightly out-of-touch aunt who lives in Florida. It was a Michigan State shirt (large - my size) she found at a yard sale.
Good luck to you, too!
