Wall normal grid configuration in pipe

Dears
I have question regarding the wall normal grid style:
In the Wu and Moin paper (A direct numerical simulation study on the mean
velocity characteristics in turbulent pipe flow) the mesh that they used is a bit confusing for me. In the centerline (r=0) the mesh size is 1.845e-3 and at the wall (r=1) is 9.203e-4. But at the distance a bit far from centerline (r=0.409) the mesh size is 9.083e-3 which says 5 time bigger than cenerline. Could please someone help me and explain me the reason.

That must be a typo.
