Brian, not doubting you at all. I have been trying to figure out the system for years. I post all my scores and play by the rules, play it down and everything out. Have not had a decent round in about 2 years , so no need to not post them. I work a bunch of junior, amateur tournaments and I can recognize good golfers. I stopped playing in skins because recognized some that were there solely for the skins. Have competed with some that of I was on the top 4 and were paired with them, after 2 shots, I knew whatever I shot, they would beat me by one on the last hole.
I do think that the WA has cleared this up the last several years. Only way to eliminate cheaters odds play in the gross division.
