C.O.R. (COEFFICENT OF RESTITUTION) The measurement by propelling a golf ball from an air cannon into a steel plate at a fixed velocity, and measuring the velocity of the ball as it rebounds from the steel plate. This test allows us to determine how much of the energy in the golf ball is lost during the impact (A C.O.R. of 1.0 would imply no energy loss). MYTH BALL COMPRESSION C.O.R. Low compression golf balls produce Wilson Staff DX2 Soft 40 0.81 Low C.O.R. / Ball Velocity.

TaylorMade Burner 74 0.80 • Wilson Staff DX2 Soft has comparable/higher C.O.R. than the vast majority of competitive balls. Bridgestone Fixx 68 0.79 • Wilson Staff DX2 Soft is significantly softer (lower compres- Srixon AD333 76 0.79 sion) than all of competitive balls – and less than half the compression of the Titleist Velocity.

W/S DX2 Soft 0.74 Titleist DT Solo • There is minimal difference in the slope of the C.O.R. from 0.73 Callaway HX Diablo Staff DX2 Soft (low compression) and competitive balls (high Srixon Soft Feel compression). This indicates no performance loss at high COEFFICIENT OF RESTITUTION 0.72 swing speed, and a potential minimal performance benefit at low swing speed. 85 90 95 100 105 110 115 120 TEST VELOCITY (MPH) MYTH Low compression golf balls are for play in 0.805 low temperature. 0.800 FACT 0.795 Low compression golf balls are for play in 0.790 ALL temperatures. 0.785 0.780 • Wilson Staff DX2 Soft Soft has higher C.O.R. than the com- W/S DX2 Soft petitive group at temperatures between 7°C and 24°C. 0.775 Average of Titleist/Callaway/Srixon C.O.R.
