Good question, John. As usual!

You would still have a straight line Angle of Approach, but remember, with 10-5-A, you Trace the true Geometric Plane Line. And when you do this, the Clubhead Covers its curved Visual Equivalent, the Arc of Approach (the Clubhead Blur through Impact and Low Point). It therefore cannot Cover the straight line Visual Equivalent, the Angle of Approach (also through Impact and Low Point).

Hitters using 10-5-E as their Baseline do not Trace the (Geometric) Plane Line of 10-5-A and hence do not Cover its Arc of Approach. Instead, they abandon the Tracing concept altogether and Cover the Angle of Approach, the straight line -- not curved -- Visual Equivalent of the true Geometric Plane Line.

Thanks Yoda,

That certainy clears up some fog. Awesome post!
