I also play with Gary regularly. That guy's little record book is filled with notes on courses, pin placements, wind direction and speed, Barometric pressure, relative humidity, # of other players, their scores, time of day, disc used, weight of said disc, and line attempted. The second chapter is putting. First is estimated putt distance, putter used, putter weight, elevation, wind direction, missed or made, where it hit the chains, type of putt used, and aim point. Then he walks off the distance to verify his estimate.....
I made this all up but knowing Helmut I'm pretty sure its not far from the pin.....
He writes something down each and every hole!!!!!
