  We conduct a careful analysis of the data provided by Krogstad & Davidson
(2011) and show that their data do not support their conclusions. According to
their published data, their decaying approximately homogeneous isotropic
turbulent flows are, invariably, clearly different from Saffman turbulence; and
very clearly marked differences exist between the far downstream turbulence
behaviors generated by their conventional grid and by their multiscale cross
grids.
