Hello Oscar, I have read your book "You can play tennis in 2 hours", and found it very instructive. I find that most people who claim to follow or teach your method are misinterpreting your advice on preparation. You have clearly said that the body reacts first, and the arms react later. I take that to mean that the unit turn is done early, albeit with the racquet still not taken back fully (it is still facing forward). The final take back, racquet head drop, and the forward swing are done as late as possible, so the ball is hit at the right spot with one continuous motion - right? An although you say to do this after the bounce, well, I take it that one has to adjust a little based on depth and pace. What people seem think is that the unit turn is also performed after the bounce, and that in my opinion is an incorrect interpretation (except perhaps for really short balls). Could you clarify this for me (and everyone else)? Thanks!
