hi oi think most golfers would play in the low 70 but some i dont think would do it often just as some would play in high 60s more than others, i do think everyones game would be so much better but think some will go back to there bad habits like we all do after we pass our driving test and start driving on the roads. the ones that keep working on the basics and on there game will stay in the 70s, but i think most will get to 70 and like greg said not all will have the same drive to be the best.
