Yeah I think you're right. Although I'm wondering if we were actually given individual dates for the deadline to submit any updates, based on when we were placed on the alt list. I say this because my email states that I have until march 22nd to submit them. I also spoke with admissions today, who said that something received prior to March 27th will likely be considered by the committee. So my guess is that we have our own individual deadlines, (maybe a couple weeks or so) and the hard deadline for when they stop accepting updates from everyone is March 27th.
