Missed this when you posted it back in July.
Excellent post. Good job on digging up this stuff. I believe that Dr. James Poole first wrote about this stuff back in the 1960s for a college thesis. I recall seeing that paper on the interweb back in the 1990s but I suspect it is no longer accessible. At that time, Poole wrote primarily about forearm pronation and the mistaken over-emphasis of the wrist (flexion).
Poole was a world-class badminton player who played internationally primarily in the 1950s thru the early 1970s. I believe that he was also very competent in tennis, basketball and baseball and was well acquainted with the mechanics of all these sports.
