Mean curvature functional evolution of the expanding domain in the biscale partition models illustrated in Figs. 1 and 2. VQZA curvature evolution is shown with + symbols and the standard N-body EdS constraint (interpreted relativistically, not in Newtonian terms) is shown by curves. We hypothesise that the smooth curvature evolution (+) is relativistically more accurate than the sudden drop to flatness (solid curves) of the standard model.
