To add to that I think it's clear if you had the potential to call in a favor (because it's not like asking a favor from your colleagues is "free", you don't want to do this for anyone) you'd want to make sure that said applicant would absolutely go there.
I think in this situation it's not particularly difficult, because
@ridethecliche doesn't have a ton of merit aid at school X (correct me if I'm wrong). THAT is a conundrum. Aka accepted to Cincinnati or something with full tuition scholarship, but really wanting to go to duke. Duke is DEFINITELY your #1...but the financial discrepancy is massive so without aid you'd DEFINITELY not attend Duke...however in that case you can say "well, this school ended up being 200,000 dollars cheaper so....yeah."
Either way it sounds like RTC isn't super hyped about einstein, so if I were him I'd be happy with Jefferson and be pleasantly surprised if I got into einstein (I'd also write love letters to einstein) but I wouldn't try to call in every favor in the book if I wasn't sure I'd go to einstein.
FWIW RTC my friend with nothing absolutely stellar received 10k a year at Jefferson, and that was before they received 100 million as a donation. Odds are you'll get something, so chin up and congratulations!
