I used to play with one guy that was a terrible putter. Seemed like after the greens were punched he putted twice as well.
I used to tell him it was because when the greens were smooth he had a 100% chance of his off line putt missing the hole. With the greens punched he had a 50% chance that one of the holes was going to knock his ball the right direction and he would make the putt.
Hahahahahaha...........................that gave me a good chuckle. Thank you!
As for some of the other comments:
Every course aerates, and it's just a fact of life. Some courses are nice and some courses are dumps.........and the same can be said for aerating greens and how well each course performs this task. All greens are obviously effected adversely, but to what extent varies greatly from course to course.
With that said, when I used to play around a lot, I'd ALWAYS ask each course when the greens were aerated before playing during the spring/fall when the greens were getting punched. All courses aerate at slightly different times and it's possible to completely avoid freshly aerated greens if you plan your golf wisely. Of course, it helps if you live in a populated area with many golf courses.
