So I don’t feel like I should – I can tell you right now what happened or what I know. But the R&A didn’t do their job in keeping it private. “To make it fair they should test everybody. It’s not to make sure our stuff is conforming. Our job as players is to show up to tournaments, put on a show for the R&A and for the Tour and to handle our business. “To my best belief, I was playing a conforming driver. Schauffele got a lot of unwanted attention after it was revealed his driver was one of the four that failed the R&A’s testing. So during testing, which is carried out with a pendulum-like device calibrated by the USGA, the time the golf ball and driver face are in contact is measured in microseconds to give a characteristic time, or CT, value. This then becomes 257 (plus 18 tolerance) outside the impact area. The Rules of Golf state that if the ‘characteristic time’ value at the centre of the clubface is greater than 239 (plus 18 tolerance) then the club is non-conforming. So what makes a driver non-conforming or, in layman’s terms, illegal? You might remember this all blew up during the Open in July, when the R&A found four non-conforming drivers during testing at Portrush – most publicly the Callaway Epic Flash Sub Zero belonging to Xander Schauffele. And, according to Reuters, Corey Conners, Robert Streb, Jason Dufner, Michael Thompson and Mark Hubbard were among the players whose drivers did not pass the test.
