Before you putt, stand behind the ball and look at the hole, then take a practice or “feel” stroke to develop good rhythm. This helps your body prepare for the actual stroke you are going to make & helps your distance control, especially on long putts.

on long putts I look at the hole and not the ball….surprised at how accurate and close I come to the hall making the next putt much easier
Though I have been doing this “feel” for some time, I found that the longer I waited to take the actual stroke after my practice strokes, the less likely I was to get the ball to the hole. The longer the pause, the less I “remembered” the feel. Rushing to putt created the same inconsistency. Developing a tempo between practice and the putt itself has been very important to my results.
