ARe you talking about 10 business days? My gut feeling is that the earliest people usually get responses is about 2 weeks after the 15th, depending on how the weekends work out. For this particular month, I would be beginning to expect answers around the 30th, but more like May 3rd.

I also have the feeling (not backed by going to look at older posts) that some of those early decisions calls/emails come to families that already have a DYS.
