I was browsing through the blog just now and read a post from 2010 about finding the speed of a putt. That is, if it’s X feet to the hole, how hard do I hit it?
There was one comment in that post that not only gets you in the ball park, it puts you right next your seats, to extend the metaphor.
Go the practice green and learn how to hit putts of 10 feet, 20 feet, 30 feet, and 40 feet. Learn to feel the stroke that puts the ball right next to the hole from each of these distances.
Take touch, which can vary from day to day, out of the picture by making the length of your stroke your sole distance generator.
If you are between distances, say 25 feet, make a practice stroke with the 20-foot stroke, another with the 30-foot stroke, and then one in between, which you will use for the putt. You would do the same if the putt is 20 feet but uphill, or 30 feet and downhill.
The more you calibrate your golf, the easier it gets.
