Impact Plane Line and Low Point Plane Line

[Yoda]

Dear Yodasluke,

How far downplane does your right shoulder move to start the downswing (first stage rocket) before the right arm drives (second stage rocket) the #1pp all the way down until low point is obliterated?

JG33,

While we await Dr. YodasLuke, let me apply this tourniquet:

You obliterate the Impact Point Plane Line. You only touch the Low Point Plane Line.

Unless, of course, the Impact Point is the Low Point. In which case, you obliterate neither.
