A small correction in your video, 1:28, no player in modern tennis leads with the wrist, this would imply an arm dominant swing. As you mentioned earlier he uncoils the body with legs and the arm is moving passively from the uncoiling effect. The same thing with butt cap facing the ball, this is a biomechanical biproduct with ATP forehand and does not occur by actively pointing the buttcap to the ball. I know its hard to explain a swing but maybe my comments will help. At 1:34 on this particular forehand the hand and racket tip are at the same height. As you see he hits other forehand the racket will be below his hand and vice versa on high forehands. Nice analysis otherwise. I wish I had this level of racket head speed but it will never happen.
Thank you very much for your comment! Regarding the head speed, I started doing functional training with medicine ball, hope it will help. I think technique should be combined with functional training.
