I've recently learned pronation in serving and it's a wonderful feeling! My serves just got more powerful and controlled at the same time!
I do wonder if it matters how fast the pronation is done. I've come across some video that say that the twisting of the forearm in adds angular momentum to the racket for extra power, and I believe it (having a background in Physics). But I'm just not sure how much additional power it can add, percentage-wise. I think I've experienced some of it, when I got lucky a couple of and my service motion just clicked.
At this point I'm already happy with just pronating gradually. Hitting the ball in a pronated arm gives a feeling of solid and controllable impact and has already added noticeable mph (and kick, for kick serves) to my serves. Any extra coming from a fast pronation will be welcome for sure!
