Suggestion from a friend: Why don't ADCOMS upload dings/waitlists the day before, then telephone admits on D-day? Is all this suspense necessary?
Kellogg (accidentally?) did that in R1 and I think it created more suspense since people with no updates freaked out waiting for a call or an update. I think Anderson uploads results the night before but the disappearance (or not) of recommender information more or less gives away the result.
It might just come down to resources and whatever system they have in place. Work in admissions one day and find out the secret?
