Resonance as a Means of Distance Control in Putting
  This paper extends an initial study [arXiv:0903.1762v1] where it was shown the tempo of the putting strokes of accomplished golfers can be explained by assuming these golfers drive their biomechanical system (i.e. golfer and putter) resonantly. In this paper it is proposed that a reason for driving the system resonantly is to simplify the problem of distance control in putting.
