Pre- and post-virialisation EdS-normalised scale factor evolution a_eff∕a_EdS for a biscale partition evolved using the VQZA as motivated in Sect. 2 and defined in Sect. 4. From bottom to top at t ≳ 7 Gyr, the arbitrarily chosen dimensionless values of the average initial invariants (at initial scale factor) in the expanding domain are , , (“planar” case); (0.01, 10⁻⁴∕3, 10⁻⁶∕27) (“spherical” case); (0.01, 10⁻⁴, 0); and (0.01, 0, 10⁻⁶); respectively. The sharp transitions from pre-virialisation to post-virialisation epochs are clearly visible and occur at roughly 7 Gyr to 2 Gyr, respectively. Prior to virialisation, the QZA is fullycompatible with EdS global evolution (which can be thought of as Newtonian T³ cosmology), especially in the planar case, in which the QZA is exact in the Newtonian case.
