Good posts. I can corroborate to some extent based upon comments made by interviewers, etc. From what I understand, they do take many factors into account. It is a lottery, but the chance of you receiving your top choice is based upon your rank as an applicant. It’s like the nba draft - high test scores, gpa, interview score, and the like, result in a few more scraps of paper with your name on it thrown into the metaphorical hat. In addition, due to complaints from previous classes, late acceptances/wait list acceptances act to fill open spots at satellite campuses. It’s sort of like a mini version of the match/soap.
