OK, I played nine holes at Mira Mesa today and I missed three makable putts. Two I didn't hit with enough speed and they broke across the face of the hole and one just broke more than I thought it would.
Because of this thread, I took a 4 foot steel ruler with me to check of the lumpy donut or the Villages cup.
Here are the photos that I took after missing those putts. One is the second hole, one is the fourth hole and one it the ninth. I made an eight footer on eight with just enough speed to get it to the hole. The Villages cup seemed to have no effect on that one.
I did not miss those putts because of the Villages Cup. It's more likely that they were missed due to the rotation of the earth.
