Hey, this was me! It was a total coincidence, I wasn't watching this thread or anything. It was an unofficial acceptance. If you're curious about my stats, I'm going to put them in my signature after I write this.
But if I were you, I wouldn't worry about it. I got the impression that they wouldn't be done making decisions for a while yet. They said it could take a few weeks for me to get my official offer letter. Good luck, and congrats on Berkeley, Yale and Stanford!!
