By this same line of reasoning, we can show why short-game vertical hinge actions are more often than not unnecessary. As the stroke gets shorter and the plane angle steeper, your angled hinge approaches a vertical hinge - all without the deliberate conscious manipulation (and danger) that comes with it!
