Watching Pro's hit the ball in person should have been at the top of his list when he embarked on this adventure so that he could get a perspective on how well they hit it. Seeing how the Pro's hit it gives the amateur golfer an idea of what a good player's shot looks like. I haven't read all 90+ pages but it doesn't seem Dan has a very good plan.
Unless we are playing a competitive match, I always tell people they can play however they want, don't need my permission.
Just don"t try to suggest you shot xx to beat me when you didn't count those drops and follow all etiquette.
