There is no "muscle memory" in the hips that enables them to correctly turn in a precise fashion (or in shoulders, or in any part of any human).

That's just it with the hands controlled pivot. Do you move with brain attention to the hands or the hips or the shoulders? You can hit the ball by doing both. What method will be more precise? There is a reason why you do most everything in life through your hands.
