Checking Green Speeds

For the last month, we have been checking and recording green speeds. We have 3 greens that we check daily so we are staying consistent. 

We have a USGA Stimpmeter that we check them with. It is a 3' long piece of aluminum that is v shaped with a groove near the top for the golf ball to rest in. You place a ball in the groove while holding the Stimpmeter low with one end on the green. You slowly raise the end with the ball until the ball starts to roll. Once you roll 3 balls, you measure the distance from the ball to the end of the Stimpmeter. Then you roll the balls back in the other direction. Once you measure the distance back, you take an average of the two distances and this is the green speed. Today they are rolling 9'5".
