Did anyone watch? I caught it mid-stream. I don't know if he defined what constitutes a one or two-plane swing, though I think it has something to with how upright you are. The more upright the golfer is, he advocates a 2 plane swing. Jacobson is now a 'one-planer' and he is more leaned over at address.

There are numerous post around relative to Hardy's book and a Golf Digest article. I have been spending some time with them because I thought there may be some connection between Shoulder Turn 10-13-C, Rotated and his SP and also for general education. Hardy evaluates six categories with Posture being one. While the book photos show an obvious difference in the models, the positions in the Jacobsen photos are not as dramatic as when Hardy demonstrates which may be the reason PJ was not used in the GD article. Jacobsen's forward bend is too steep to satisfy Hardy's 35-45* SP standard which could be a factor. Arms are another category and for SP Hardy wants the left parallel to the shoulders at the top but above them for DP. In both models, the arms move to the top in a steeper plane than the shoulder turn which could question the descriptor "single." FWIW, and acknowledging that people see different things in drawing these line, it looks to me like PJ may be close to the TSP in the move down but not Hardy.
