Mechanics Creep

[Paintguru]

I'm pretty sure I do all four to some degree. Signals are meant to communicate information. IMO, as long as that information is being communicated, most should be fine with it. Obviously there are mechanic sticklers out there, but as others have said, I'm not sure why anyone should care unless it impacts the actual game in some way.

I'm more worried about both referees on a 2-person game being on the same side of the court multiple times, as I saw last night.
