"the stretch direction is always below plane"

Would this mean if the left arm was a piece of string we would be trying to pull the string tight NOT along the line of the shaft, but to a point on the ground below the shaft?

Thanks in advance

The tug is on the primary lever- the left arm, NOT on both levers, so not along the shaft. The shaft (the Plane) needs to be released (the clubhead) rolled on a straight plane line (clubface). EA on the shaft would be a big brake- even for a Hitter. EA is structure- Flying Wedge glue, not a power source.

So the downward inline Extensor action goes below the plane (shaft)- and whatever power accumulator number three angle it still has.
