I recently interviewed and we ask Dr. Sposetti specifically on this. She said last year I believe that there was only one person pulled of the waitlist. Supposibly the guy got in, fell in love and moved to another state to follow the girl. She says it can happen but it's really rare people whom are accepted to UF would give up their spot. You have to realize that 70+ are florida residents and a lot of them are from UF so they will likely choose UF if they have a double acceptance.
