The Putting Arc started in the inquisitive mind of VJ Trolio, a young teaching pro at Old Waverly Golf Club. In the winter of 2002, VJ noticed that if the putter is swung perfectly “on-plane” along an inclined plane, that the putter head appeared to move on a curved path, when viewed from overhead.
Interestingly this curve was a very specific segment of an ellipse, and the formula for this ellipse was first calculated by Appolonius of Perga over 2000 years ago in 200 BC. The patent for the Putting Arc is based on this formula.
