There may well be a few, hopefully very few cheats out there, and probably amongst the 'not very good' player ability.
Why not very good? - well even if there is an auto-dinger, even if the meter can be slowed down, thats a small factor in playing this game, the skill is in course management, selecting the correct club, the correct shot, the correct spin, aiming correctly, selecting the correct power, adjusting for the wind, playing from the fairway, rough, bunker etc, then making the ding, or getting close to the ding, maybe even missing it on purpose to aid the shot.
Someone without the skills to play the game may hit the ding with a cheat program, but they won't beat a good, probably even average player, so don't get too hung up on people who post great scores, they are probably a great player, or a multi lol
