wayneacampbell: ascertaining the correct aim point
Most switch from full to pitch shot. Then hold click to reveal the slope indicator. It's ten yards wide. Sometimes you get it at an angle. If diamond shaped, it's close to 14 yards corner to corner. For true down and dirty quick, I sometimes just use the blue triangle in the hole inset. I figure it's right at 24 yards wide.
Hope this is both what you're asking and is helpful.
Good Luck.
