^^ It would be hard to hold the racket by the handle on a table top machine while you are pulling tension with a drop weight. Also correct me if I am wrong, but wouldn't it be better to mount the racket farther to the top of the racket so you would reach the center point faster?
When you're dead you don't know you're dead. It's the same way when you're stupid.
