I noticed during playback of a recording that there was a shot where a forehand was used impossibly. The racket went back for a backhand, but then a forehand animation replaced the backhand animation, but the shot return was as if a backhand had been used (and a backhand should have been used). Here is a picture of the backhand take-back and then the forehand follow-through:
From this last photo, you can see from the direction of the ball that the shot could not have been hit with a forehand:
Also, here is the video, in which the shot occurs at CC 3 30, Jer0 0 30 (this is the score on the scoreboard):
I have also noticed once when retreating to return a ball that was between the baseline and the back wall that my player swung while running back to get the ball (did not hit anything and kept going back -- the ball was very close) and then swung again and made contact. I have that recording somewhere, but it would take a while to find it.
