Hi guys,
I'm a current student at Ross, just reading this to kill a little time while on spring break.
Last year calls started going out two days before the deadline. All calls finished on the day of the deadline in the early afternoon, and then all the ding emails went out around five on the day of the deadline. There is NO order in which they make the calls, not by last name, not by region (although they will make an effort to call during business hours for internationals in different time zones), not by scholarship/no scholarship... nothing.
Best advice to you all is to have a great weekend with your friends and family and get back to forum-hawking on Monday around 9. As soon as the first call goes out, you'll see it here or on the BW boards, at which time you can recommence stressing

Good luck everyone, hope to see you next year.
