Isabelle Chrun's Tennis Serve ~170 km/h

At the Montreal Rogers Cup, there is this stand where we can measure the speed of our tennis serve. I am disappointed that on that day, I couldn't serve faster than 104 mph (167 km/h). I don't want to make up excuses here, but you have to agree that I would serve better with my own racket and some shoes...
Well, that's what I've been telling myself :)
