New Star 3, Star 4, and RDC videos

We've taken the 52-minute Babolat video that covers the Star 3, Star 4, and Racquet Diagnostic Center (RDC) and split it up into targeted sections. USRSA members will find these videos on the Machines page (in the members-only section), and on the Calibration page (ditto).

Updated: Racquet Mass Mover calculator

We've updated the Racquet Mass Mover calculator to include First Moment, both for the starting specs and for the racquet with all changes to mass and mass distribution.

We also reformatted the calculator in the hopes of making it easier to use and understand. Check it out!
