yeah, just wait, but don't dwell on it too much. you guys are going up against incredible odds here which are out of your control, and are no reflection on you as a student or as a person.
for now, don't even think about Caltech
it's probably unhealthy, all that numbers analyzing, percentages, postmark dates, etc, etc, and it's best to make sure you're happy and excited about the amazing school you're (probably) going to attend. I mean, no sense letting some facebook group's membercount build you up, just to let you down.
right?
...and if it works out, then you're in a very enviable position. If not, no biggie.
