I agree with Zag. Like his experience, the majority of my offers were in October. I will add that I did receive a few in Nov, and then some late offers from waitlists in Dec and Jan, but the vast majority were in Oct. Additionally, his explanation of the ridiculousness regarding minutes and hours making a difference in obtaining an interview are unfortunately true as well. I missed 1 offer because I responded after 30 mins instead of 29, or 28 or whatever the magic # was that day. For another program, I responded within 20 mins and got my 4th choice for interview day. The bottom line is that this is a competitive specialty with a homogeneously well-qualified group of applicants, and therefore some programs are happy to fill interview spots with whomever responds the fastest once they've initially filtered applicants. Not everyone does this, but it's difficult to know which programs do, and it'd be a shame if one of your top choices misses out on the chance to interview you because you can't get to your email. I hope this confirmed some of Zag's points, and good luck during this year's cycle.
