No you hit one of problems on the head. If for example you came to my private court in SF and wanted to work on your forehand, we would film you and look at you side by side with some pro models but focus on a limited number of key positions--as few as one or two.
You could have as much or as little of the detailed technical info I am posting as suited you.
Another paradox is that despite it's tremendous complexity all the clear verbal understanding in the world won't get you a better forehand.
We would use the video to create actual, precise physical positions with checkpoints which you would master and you would then create internal mental images of them--this creation of kinesthetic feel and mental image is the real key to creating change. Most people need some of the explanation but for others it is simply interesting and fun--or of no interest.
