In the framework of the general spin formalism based on the symmetry properties (”dynamic amplitude””approach) obligatory kinematic factors arise in the expressions of observables. These spin structures for high energies give a small parameter that orders the contributions of helicity amplitudes to observables. Such a ”kinematic hierarchy” predicts for pp elastic scattering at high energies and large fixed angle (90°) a simple connection between asymmetry parameters and even numerical values for them.
