Question: is this a 2) strong advice, 1) weak advice 0) no advice?

As a possible mechanism for the reduced pain after robotic hysterectomy, Chiu et al[17] explain that the chance of using the abdominal wall for leverage is decreased because the robotic arms pivot at the port sites and move/rotate around a fixed remote center-of-motion, thereby decreasing mechanical injury at the abdominal wall.
