True, trial and error, experience, intuition, I guess is the way most of us go. And from shadow swinging myself, and watching others, it seems acceleration through strikezone is normal (and I am not just talking about Marion Bartoli here...). Also it seems intuitive that you apply more momentum by swinging, accelerating, dare I say pull through impact, than by just letting the hand passively follow the racket at a pace previously achieved.
