Notes: the reason I suggest a cube is that we can get a good guess at the "sharpness falloff" based on the distortion of the visible edges, which we could reasonably agree to be the standard for measurement. ( If the cube on 0, 8 is fuzzy around the edges, then the sharpness measurement would be expressed as 8 pu's from focus to edge )
