Full-sum comparison from bounds on its two coefficients #

The coefficients here are the sum of the actual carrier Morrey norms to the 6/5 power and its radius-weighted multiple. They are distinct from bounds on individual clipped cell integrals or the actual total time mass.

Bounds on the two coefficients of the one-sided expression imply its comparison with the enlarged numerical constant.

Bounds on actual clipped cell integrals and actual total time mass give an AE pressure-gradient producer directly, without replacing those two coefficients by powers of its Morrey norms.
