Not an attending, but thought I'd chime in. I did this with shifting around a couple letters as I, like everyone else, overanalyzed the process to death. I had no intention of just slipping more letters in, just wanted to play with the mix of which ones I sent where. The programs had already downloaded my letters throughout and obviously the de-assigned ones didn't disappear from the pages in my files. I was able to see my file at a couple programs and they had like 5 letters and no one seemed to care. I think as Dr. Levine says, they probably don't even register this as a thought as they pour through stacks of applicant files.
