Thank you very much for comments about the article. But I think you missed the main data from the article. The diagram below illustrates the racket speed which produced by the pronation and internal shoulder rotation |VLH|. If the beta angle = 45 degrees, |VLH|= 105 mph. And this speed is created practically exclusively by pronation and internal shoulder rotation. Tiw these motions are the most important.
