OK. There is another thing. You said about the drop shot issue that onces the animation has started say for a forehand drop shot when I was trying to get into position to hit a backhand drop shot that it was too late (maybe I had not prepared early enough). Well, there are times when a forehand animation starts and at the last moment the strike changes to a backhand, like as below:
In this case, I was trying to hit a backhand shot, but the game prepared as if I were going to hit a forehand shot. Then, at the last instance, it was able to switch around somehow and hit a winner with a backhand passing shot.
Looking at the replay I can see that when the incoming ball was hit by Nadal, my racket was about in the ready position. I was just to his left when he hit the ball (directly in front of the meeting his racket). Just when he hit it from his left to my left, I started moving my player to the left so that I could get into position to hit a backhand passing shot. As soon as I started moving to the left, the racket went back as if I were going to hit a forehand shot to my right (and probably had I not moved the player anymore, I may have been able to contact the ball, but it would not have passed Nadal). I kept moving over to my left, and as you see the animation changed at the last instance. So sometimes this works out OK.
