I would agree with that and I guess that is what I was trying to get at. Spin is easily seen but only one part of the equation.For the amateur golfer, I think its overthought. The average golfer (lets say handicap from 8 to 18), can have spin change upwards of 3000 rpms per swing and up to 1200 rpms on good contact swings. But its an easy number to see and understand, so it becomes a topic of buzz rather than the rest of the scenario.
