Well, my experience is that it didn't help a bit. I got all my applications in early, and I come from a top 5 program, with numbers *very* similar to yours. So far, I have not been accepted anywhere that I had less than a 75% chance. In fact, I'm on hold, at my alma matter, with 80% odds.

Sorry to hear about your run. Well, specifically Boston U. U got in, with those *exact* numbers (I'm a EE) back in December. It's a bad environment out there for the applicants.
