I’m a 13 and I can’t hit a driver consistently within a 40 yard window. I know single digit players that can’t do this. It’s just basic mathematics really. A 40 yard window at 280 yards is not the same as a 40 yard window at 230 yards. The margin of error is much smaller at longer distances.
High handicap players will struggle if they played on a cow pasture. That part has little to do with swing speed.
Swing speed can tell you someone’s potential, but if I gave you two player’s swing speed and nothing else, you’re not going to be able to pick out who the better player is, or the player that hits the ball farther on average.
I swing faster than Jim Furyk, but he is longer than me on average off the tee and far more accurate.
How is your partial wedge game? Serious question.
It’s not that easy to dial back or just simply swing slower. You end up changing all sorts of different variables, and guess what? You still hit misses.
I was playing at a resort course with a road through the middle to access cabins on the other side of the course. While preparing for a shot a minivan stopped on the road near us to let 2 kids out to run across the fairway to go feed geese on the course. Those parents are idiots.
When I say "know where it's going", I mean within a 40 yard window. Unless you are playing very difficult courses, then you should be able to stay away from OB and hazards with that. And if a high-cap is playing those difficult courses, that might be why they struggle.
You are absolutely right on the ball speed thing, but generally speaking swing speed is a decent indicator of distance.
I agree with most of what you said otherwise also, but I think if I was making inconsistent contact to the point of it costing 2 strokes a couple of times a round, I would dial it back. Whether it's from 120 to 110 or 100 to 90mph swing speeds, slowing the head down should make it easier to get consistent contact.
