For example, if you practice golf without hitting the ball, you can keep the smooth swing, the tempo and the in-in swing trajectory, but when you practice over the ball, the swing tempo will be faster without you knowing it. As a result, the deviation of the direction and flying distance of the ball increases, and the pitch may also be irregular.
