This is a great series. What I think is nicely innovative and demonstrative is having a willing person who is trying to improve and going through the evolution of his swing to the point of putting all the points together. And it is realistic because once you mention a new facet of the swing, all is forgotten to focus on this new point, and you have to go back and forth reintroducing past points again. This is how we learn, not perfectly all at once, but in fits and starts. Brilliant.
