There is an advantage...I don't think it's quantifiable as a home visit or a campus visit, but the way it was explained to me, all of your efforts are amplified. I wasn't able to get an answer from CS about whether your effort is amplified at a 1.2, 1.5, 1.01 rate or anything like that. CS did say that the advantage is easily overcome, so it can't be that much. My best guess is that it's worth a grade step in prestige.
