OK, so lets say my approach is 33 feet downhill. How much should I subtract using iron or wedge? Do I divide by 3,4 or 5? 3,5 feet = 1 yard for irons doesn't help that much. I already knew it was in that range. I just wanted to know what calculation others use. If I divide 33 by 3 I get 11, divide by 4 is 8.25, divide by 5 is 6.6 yards. Big difference.
