Generally speaking, positioning refers to the accuracy of the targeting stars in FPS games from moving to stopping and completing the targeting process. That is to say, as the saying goes, "where to hit where".
Resistance under Stress Response
For example, if you suddenly encounter an enemy at a corner of C, and your first reaction is to quickly move the sighting star to aim at the shooting, then the strength of your wrist will automatically increase because of the tension caused by an emergency, and the magnitude is absolutely greater than when you move the mouse normally. Much more, so the pressure on the mouse pad will naturally increase, in this case, the resistance of the pad itself is the resistance under the stress response.
