I have dug up a couple of driver swings from May of 2015, which was the first year of the MCS Classic Golf Swing model as it is today (with one change from 2015).
In the summer of 2014 I had begun my “Ben Hogan Project,” which gave me so much insight into Hogan’s true pivot action (not the one presented on television and in print or online from clueless pundits) that I implemented it into my model orthodoxy.
