Retscev (Ret+Scev) is a form of Z* Physics, in which it defines the base of spin. In the SDS (Stank Dank Spin) when true spin is enacted, Retscev follows through, this occurs because without a base spin, the SDS would simply spin in a classical form. The ratio for Retscev is 19(Ret):21(Scev). When this either the Ret or Scev ratio is enacted a cycle spin will occur, however when both occur a true full spin will occur. Many users of the SDS learn how to define these ratios and how to enact them. This ratio can also be transformed into a shape and when QX is applied, this shape become a circle with 2 corners (Don't try to think it, you're head will explode). Users of the SDS try to enact this shape and form it into a classical cricle, this allows their brains to focus more on the actual ratio rather then the shape or form. If this shape is not enacted the form of the object that the ratio of Retscev is being applied to will simply either dissolve or contort.
