I don't understand how these guys can measure these angles with any sort of reasonable precision.
They are looking at 3D pictures and we don't know if the camera is totally square with the camera and they draw lines and claim that this guy has 37 deg of turn, lift, spine angle, etc.
He says that Dolby has 35 degrees more shoulder turn than Tiger.
Huh?
He might be making a bit longer turn, and you can see his right shoulder behind his head (much like Garcia). It does take a lot of flexibility to do this, but you can also see a little of Tiger's right shoulder near/behind his neck. Again, I stress the camera placement issues. There is a lot of perspective here and the viewing angles are all relative.
I don't think these guys have an understanding of plane geometry. You can't just draw lines on a 3D surface then project to a 2D computer screen and call it a day.
