In order to help others, you need to know their individual situation, and goals. For instance, in my case, in order to shoot my average, my answer to you, would be 9. if I can't 1 putt every green, I would have a real hard time shooting my average. If you're trying to help someone reach the master tier, then your answer would be 14. That's assuming that you are on the greens in regulation. Of course we are all going to wish that we could 1 putt every green.
