I have watched all the videos. i have read the pdf.
I have emailed Planeswing who couldnt explain
it, but said watch the video. The written instructions
say attach the cord checker at the midpoint. There
are attachment points on the tubing at the midpoint.
In the video, he says "im tall, so i set the pole height
at zero. "" . Further on, he attaches the cord
checker well above the attachment points.
Another video { cord also above attachment points} says, while
setup with the long slider pole, """ the tubing should pass thru
your biceps"". He also says "" This is your swing plane. ""
How is this helpful ? The tubing can pass thru your
biceps when set from a horizontal to a vertical angle.
Now if he switches {doesn't happen } to the shorter pole
and would leave the cord in place, he wouldnt be able
to reach the tubing with the pole. The cord checker
cannot be in the same place with a much shorter pole.
We all know a wedge is swung on a steeper plane
than a driver. This thing is useful for stretching and
muscle memory, but please what's up the magic thinking
