I can imagine the frustation that those not invited are feeling. In the same boat for Stanford, Kellogg, and Yale.
But the way I see it, no amount of statistical analysis really matters. Whether there are 50% invites yet to be sent out or 0.5%, what matters on which pile the Adcom places my application. I doubt statistics determine the pile I will land up in, considering both me and my app are unique (atleast I hope they are).
StanU, say you love me too
