Last year, I applied 13 places and followed GC pretty closely. I did the thing where I assumed implicit rejection from places that had sent out their acceptances. Turns out that one of the places that I thought implicitly rejected me ultimately accepted me (no waitlist either) on April 1. Ultimately decided not to go, but served as a good reminder that I should not be putting too much stock on the implicit rejection thing. It's definitely a bad sign if you see a bunch of acceptances go up, but it is by no means a dagger. Also, this is a particularly weird cycle. More schools may do multiple rounds of acceptances / rejections (see Northwestern last year).
