Ha-ha. True - my GF analogy was not a great one. I guess if they provided an extension to anyone who asked (and then posted about it on GMAT Club), then they would have a de facto extension for everyone.
Fit does not show up in Rankings. Yield does.
P.S. interesting about Sloan scheduling the admit weekend so late... as i said, the admit weekends are a show and you won't see all of your classmates either - you just see the R1 folks who may or may not enroll, so you may see an arrogant Stanford admit who stopped by to check Sloan out and totally gave a bad vibe but you don't know that. He/she likely won't attend. The same way, so who will cannot make it to the event, and R2 folks are not there - i am really struggling for a good analogy here - maybe like trying to use a spyglass while riding a horse... I think the events are great.
Anecdotally, from my weekend, I only remembered one person who was insecure and came off as an arrogant duche and totally turned me off. He was admitted and said he was going. Made me reconsider my decision - i kid you not. He turned out to be a nice guy, not particularly bright one but nice, funny, and we spent a fair share of time hanging out. Another guy who was really bothering me during the first week of team exercises and team building turned out to be my roommate 2nd year. If we don't focus on the fact that I am an unreliable witness and can't read people, I could argue that at these events and during the first few weeks of BSchool, everyone is uncomfortable and everyone is a little insecure. Most likely, you won't really get a real feel for that elusive fit Kellogg talks about.
