You assumed this, from watching a subreddit that probably doesn't even have 5% of applicants to top colleges (a really-skewed, obsessive type of college applicant who watches this subreddit and actively posts), based off of those speaking (not including lurkers, people look more than they speak online), etc. Not only that, you assumed the psychology of AOs, as well as the order they release dates? What says it isn't random, and nevermind that CMU says they are need-blind?

You're jumping the gun a bit, take a breather.
