Don't forget, you also have to have your calculations correct in the first place for the pin to be centered in the circles.
If you don't aim correctly for the side vector of wind, your pin will not be the center of your circle. If you miss the calcs by a yard, your center will be a yard off the pin. It's possible your circle doesn't even have the pin in it. This is why heavier winds become more challenging to score. You can carry your spot, hit a hump, and shoot right off the green, too.
These circles are a concept, people, to help you understand the variance within the game. The formula, although great, isn't going to be your solution. It still comes down to practice, experience, dinging your shot, and knowing your course so well you know where you even need to put the ball before you swing.
