Thing is high handicap golfers, even those that occasionally hit it far, lack consistency. Their mishits are just as often short as left to right. Playing up isn't going to magically make them start playing precision golf tee to green. I see people chunking wedges from 50 yards all the time. You can put a poor golfer right next to the green and they will hit bad shots, it is what it is. The argument people can play bad golf and still play fast is full of holes. It's not the time spent making more strokes it's the time spent chasing balls around the course that makes high handicap golfers slower.
That makes it sound like the high handicapper has no choice but to be slow. I disagree. I'm a 17 HC now and I can play in under 3 hrs easily when I'm by myself, but when I first started playing and was much worse, Ibought the cheapest balls I could find and when I hit one into the woods or somewhere that i couldn't immediately find it, I just dropped one and played on. It may get a little costly that way but i figured between me and the people behind me, who SHOULD pay for MY poor play?
