#3 The disk plane is not perpendicular to the axis and therefore the disk will appear to "wobble" on the axis as the disk and axis are rotated. This is the variation that exists for "flat" backstroke and "on plane" downstroke or other planes that dont meet #1 or #2.


Ps. Which leads to the question - Should the shoulder be on a downstroke plane to the plane line or to support the hands?

Standard Shoulder Turn....Flat Back/On Plane combo. One great description of this was from Ted Fort (aka Yoda's Luke) . Imagine your Right Shoulder being a paint brush that paints a "7" in the air......flat back and then down the plane, diagonally. Like a 7 when you look back at what your shoulder is painting. If you know what I mean. So its not describing the same motion back and down, two different motions, directionally. Its a bit counter intuitive I know, but its a bit of genius, cant tell you how much this has helped me. And upon investigation we do this sort of thing all day long, doing all sorts of motions. We direct our Hands and the Pivot responds.

To answer the question in your P.S. The Right Shoulder can only go down the Inclined Plane if its on the Inclined Plane at Top to begin with. Making for a TSP plane angle by definition, a Plane ( from Hands to Base Line) that also runs through the Turned Right Shoulder at Top. So the Right Shoulder is doing both ......down plane motion and supporting, directly pulling the Hands in Startdown. Made necessary by the Downstroke Sequence where you let your Pivot pull the inert Hands, Arms in Startdown. Since your Pivot (right shoulder) is pulling it best be pulling somewhere, ideally at the Plane LIne given that the Hands are going to follow it directly , linearly.

If I had a scanner down here (im on vacation) id do some drawings . Hmm maybe Ill try photo'ing something with my phone....
