Does the Babolat RDC machine require calibration? I was messing around with it at work yesterday trying to measure the specs on a couple of my racquets, and it seemed quite off when measuring swingweight. I was trying to check my two IG PMP out and weight flex and everything else seemed right, but I have my two racquets weighted up 365gm and the balance is around 9 pts HL. There is 8gm of lead from 3-12:30 and 9-11:30. For my two respective racquets the sw readings were 320 and 323. That seems way too low imho. Is there something I can do do adjust the machine?
