The blogger explains that Nadal usually steeper swing path generates higher trajectories while increasing the effect of his extreme racket tilt at impact. That‘s why Federer hits more flat and Nadal gets a more loopy effect. It also exposes an important fact: your swing mostly determine how high the ball flies, how steep its rising slope is when it leaves your racket.
