Why does Trackman define clubhead direction (the bottom part of the D plane - see the second page of their July 2009 newsletter) as angle of attack and "club path" when the angle of attack is already factored into their calculation of "club path"?
Does the term "club path" not include the attack angle? If so, that answers my question, however, the mathematical formula for club path I've seen posted includes the attack angle.
