THE REASON FOR THE REVERSE AXIS

To form a curved grid, two circles must be constructed. By numbering each orbit from its center point, it is easy to see how the numbers must be reversed. An orbit is considered contracting when the numbers go in the reverse direction from the first.
An axis is considered contracting when after constructing a wave form by dividing by halves, the lines of the axis are bounded by a smaller circle and cross in a web.
