The criteria used so far contained the main, fundamental drawback, which consisted in calculating the grid density of each given complex as an isotropic complex. Although the criterion with this drawback was used quite consciously, for the sake of simplicity, in view of the complexity of the operation of calculating the density of the grids, but, of course, there was always a desire to eliminate it, if only a way could be found to determine this density quite correctly, without resorting to simplifying, but still an erroneous assumption.
