Once you have the tools, would you please check distance between the morphs of the same ED grid?
For a grid w/o nontrivial automorphism, does the average distance differ from grand average?
Is it similar for all grids?

The average distance between a random grid (with no non-trivial automorphism), and a random morph of the same grid, is 1.00463 ... slightly larger.
For 10 random grids, here are average distances to "the full field", "morphs only".
Sometimes one number is larger ... sometimes it's the other.

The #9 grid, with the small distances, only has 3 UA4's -- fewer than average, by far.
Is it relevant ? I couldn't say.
