Here's an example of why I'm confused by (and suspicious of) Marshall terminology, and in this case your use of it. In a previous post, I mentioned not knowing what the term "driveline" means.
Here's your response:
quote:The term “driveline” is the line between home plate and second base running straight through the middle of the pitchers plate. He uses this term a lot because many of his tenets are to align the body parts like the shoulders, hips and elbow at pendulum swing with this line.
Today, in a response to Cap_n, you make this comment:
quote:The pro level does not recognize even partial Marshall drivelines and Marshall’s drivelines are not even recognized or understood there so how could they be preferred?
The first quote describes a geometrical line. The second uses "driveline" with some other meaning, and certainly not a geometrical one. It's hard to discuss mechanics (as you have said you wish to do) when the usage of terms is so elastic.
