This is a very intriguing video that explains what these readings mean and how a little knowledge is also quite dangerous. Have a look and remember that not all greens are built the same. At Morro Bay if our stimps are above 10 we lose 90% of our pin locations and 5 and 6 putts become the norm, while at Dairy and Chalk 11-12 is possible, but not likely to enhance the majority of our customers' level of satisfaction. In my experience, club members have a tendency to exaggerate the truth to "out-do" their friends. In the turf industry we have a saying, "speed kills!"
"Some of us worship in churches, some in synagogues, some on golf courses."
