Balls hit over bunkers are from 20-25 yards short for me. The same shot from the fairway with no bunkers in play is pretty accurate. I have never understood the short results over bunkers. If I add 20-25 yards to the shot, I'm sure I'll fly the green.
I've also noticed that distance is totally random when shots of about 100 yards are into a side-wind, either direction.
With WGT, your results are pretty much randomized. I'm guessing the accuracy depends on how much $$$ you spend for clubs and balls..
