Is this common in your neck of the woods?

During critical throw-ins in the NBA, the officials will sometimes verbally give the counts (The whole count). I'm not sure how often they do it, but they do.

Also, I was at a local rules clinic, and one of the officials there, who does D-III games told us to give the first second of the five second count (I guess this was so they could gauge how fast we were counting?).
