I use to have a ton of notes on wind speed and green speed that i picked up from the forum. It was a certain system that worked well for me and wondered if anyone has the same one. For green speeds i used a percentage of power after deducting or adding for uphill or downhill. The one I remember is for legend tournament speed was deduct 20% for uphill and deduct 25% for downhill. For wind it was add or deduct for wind speed either from behind, head or 45 degree angle. anyone use that system?
