It depends on the assignor. I know some assignors that focus on what thing and another assignor has another set of things he wants his officials to do. It can vary from the time you show up to the game, to the philosophy you use on the floor. I have heard some assignors not too happy with terms that are not rulebook terms and others that either does not care or they do not make a big deal out of it. I really do not think there is any universal answer to your question.
