You are totally wrong in your assumption. I am actually trying to understand what Tom taught. Don't mistake my assertive questioning with the idea that I am out to disprove things. People frequently make that assumption because of the tenacity of my questions, but I actually want to understand different viewpoints, so that I can increase my breadth of golf mechanics/physics/geometry knowledge.
