Well...that's pretty much true for any site, however, thus far my experience is, if you are hearing back on the date of the deadline, 99.99% of the time its a rejection. There's been only once site out of my 33 I applied to where I received an invitation on their deadline. Also, there was another poster here who posted an invitation to Baylor about a couple of weeks back. At first I had thought they may send those out in waves, but then I lost hope. Once I spoke to my friend (who works there in an important capacity), they confirmed that if I hadn't heard back by now from them, it was most likely a rejection.
