Just to add some light from last months DB. The DB was the 20th (Tuesday) and the calls didn't start going out until Monday. We were all expecting Friday but if you are not "expecting" it and it happens, then that is better. The first guys that I know of got their call late Monday afternoon and it was less than half way through the alphabet. My last name started with a T and I didn't get the call till Wednesday around 1200. One guy (last name W) didn't get his call till Thursday. Keep the faith, don't sweat it over the weekend.
PS. They block their caller ID when they call so if you see UNKNOWN, I would answer the phone.
