...However, I have a hard time understanding how the hosel rotates around the sweetspot-to-grip axis - especially with respect to the Robot-Fit golf club testing machine.
Firstly, if the toe of the club is traveling counter-clockwise (closing Clubface) and the Sweet Spot is the COG of the club, it would follow that the hosel would be traveling counter-clockwise around the same axis.
An analogy that I use is painting a line with a wide paintbrush. Start painting a thin line with the wide brush. As you continue the line, start twisting the brush so that the line becomes wider. Finish the line with the line becoming thinner. The center of the brush (the Sweet Spot) traveled on the same line. The top and bottom of the brush (the toe and heel) rotated around the center, and they travel from on-to-off-to-on the line.
Secondly, as far as the robot goes, it's been so long since I've given a robot a lesson that I can't remember what it does. All kidding aside, I made a phone call to a friend that works for a company that has one. I'll ask him about it as soon as he calls me back.
