Are you appealing because it's your number one, or because you feel burned? If it's the former, do it. If not, don't. You're going to get into a great school, is there some really pressing reason why you feel UCSF is the ONE for you?
I'm only saying this because I think appealing is an act of desperation (not quite the right word...perhaps "passion"?) that one must take when their heart has been crushed and all dreams lost. Am I being dramatic? It's because I might consider an appeal if I don't get an interview at UCSF when I apply next year (solid EC's, good GPA and TBA MCAT). I've worked there, I know people on the adcom, I know I would be a great fit (and them for me), and mainly, my entire system of support is in NorCal. It would be very difficult to pack up my family and move because I never got a chance to interview. I know I would immediately withdraw from all other schools and enroll the day after I received a fat envelope. 100% Guaranteed.
I know this process isn't fair, but I'm not sure the appeals process should be used for a "why not?" situation. I think that if you're going to appeal, if you get your interview and acceptance, you should be prepared to follow through and attend. Also, you'll probably need a very strong argument as to why it is personally important to you and beneficial to them to use their spread-thin resources on your application.
I agree, it's crazy you didn't get an interview for your stats alone, but I'm sure you aren't the only one.
Slightly off the subject of the appeal thing, were you the president of your school's Premed AMSA, or a regional director?
