I’ve heard this before, and I couldn’t disagree more. The problem is that most golfers’ “intuition” when it comes to green reading is horribly wrong. It’s not something that is usually ever taught. If anything, AP has made me think about a lot less when I read greens. I literally step up to the slope, feel it, and I’m done within 10-15 seconds. In the past, I might spend way more time than that hemming and hawing over what I think I may, or may not see.
But you do have to take some time to learn it, practice it, and then trust it. So I don’t recommend diving in until you have some time to devote to the project.
