This guide presents Dave Pelz"s approach to improving your putting game in a lucid, concise and digestible format. Pelz takes a scientific approach to putting a golf ball: he used to be a NASA physicist, and his recommendations leave nothing to vague notions of "focus" or "envisioning", but on the immutable laws of physics, which govern the effect of your swing, the trajectory of your golf ball and even the composition of the ball itself, whether you like it or not.
