 Today I found time to repeat your test.
 I did not a plot, but give you numbers : total neutron flux (forward+backward), in your 4 reference planes and for the 2 geometries.

                  1x20 cm             4x5 cm
 -------------------------------------------
 plane 1          17618               17481
 plane 2          25573               25564
 plane 3          25512               25537
 plane 4          18479               18287

This is compatible with your total neutron flux (fig 5) for layered geometry, but not for single volume.
