Not an advisor, but FWIW Auburn Panhellenic's website has the
slides from Camp War Eagle and on slide 26 it states "There are 105 women who comprise that 2.20% [of PNMs released on Bid Day from 2008-2011]. All of them neglected maximizing their preference options."
So they don't come out and say "you will get a bid if you maximixe your options" they do say the only ones to not receive a bid didn't.
