Interesting. Can't imagine "why". I recall asking a question in a tennis forum early on in my quest about whether trajectory was controlled by racket face angle or by swing path. I was surprised to learn that essentially nobody on the forum seemed to know.
Turns out that it's both, as well as some other factors. I didn't learn about it until reading Chapter 4 in "Technical Tennis" - the best chapter ever written on tennis, IMO. And, if one *really* wants to learn about trajectory, there's nothing better than this: http://twu.tennis-warehouse.com/cgi-...tory_maker.cgi
Anybody know if "TW University" is done by the same guys who wrote "Technical Tennis"?
