And therein lies the difference. I have this arguement all the time with my brother in law (who scores better than I, FWIW).

I argue that if you're going to keep score, you need to play 'tournament golf'. The rules are laid out plainly, along with the penalties for breaching them. To the point of properly marking your ball on the green, even.

If it's just social golf, then who cares what you do?
