This procedure is more right than ever wrong no matter which set of mechanics you are supposed to be using.,

In the bolded "an obvious situation, I will at least raise the closed fist, and if possible make a verbal call, too", by "obvious" do you mean no question of ordinary effort that the PU might judge otherwise?
