Since this thread started with my question, I'll ask a few more.

Regarding 3-seconds in the lane. Is there anything that causes a 3-second count to restart, similarly to how a closely guarded count is terminated? If player A1 goes into the paint for a shot, misses, and keeps putting up the rebound (and missing) for the next four seconds, what happens? Do I call the 3 seconds or is the count terminated upon a shot attempt?

As the trail, does it matter which arm I use for the 10-second count? I typically use the inside arm, but I watched a few varsity games on tv this week and all the officials used the outside arm.
