I'm an avid golfer, but I have no idea what you mean when you say "40-ball," and your explanation, including the catch, doesn't help much. Maybe you could explain it in a different way? Is the 4-some playing 9 holes or 18 holes? Do they have to count scores for every hole? Do you use handicap or not?
Maybe if I understood what you were actually doing, I'd be able to help you figure out how to resolve the problem.
"We are not provided with wisdom, we must discover it for ourselves, after a journey through the wilderness which no one else can take for us, an effort which no one can spare us, for our wisdom is the point of view from which we come at last to regard the world." --M. Proust
