Ya know, my research professor today sent me the draft of the letter he is writing me, and it is strong indeed. He's just one of those people who writes very well, and stuff. Since i've been working with him for over 4 years, he had a lot to say. All VERY positive, and nothing is made up or what not. BUt this is what i'm wondering about. If letters of rec are all extraordinary, or at least someone says something really profoundly positive, do the adcom's take it seriously? Do they give the writers a benefit of a doubt? I know that the adcom's know that all these people should say something positive about the person since these are letters of recommendation, but how much weight would 1, 2 or even 3 letters of rec that says profound things have on one's prospects on getting an interview?
