Ed,
I'm sorry, but it isn't a hole in one if it is on the range. You can hit a ball, rake one to you again, hit a ball, rake one to you again, over, and over, and over. During a round, there are usually 4 holes where you can have an ace. 4 chances per round, not 150 chances to the same pin out of one bucket of balls. By your logic, I chip in 50 times a day because I chip in a lot during chipping practice. Big difference between a round of golf and range practice. If we went on range practice skill, I would have won on the PGA Tour already. But, we don't so I haven't.
