However,I think that before being too critical one needs to take into account that the posting of scanned images for assessment of granularity is in its infancy.Furthur, I am not even sure if we are supposed to discuss the protocols here as some Photoshop is inevitably involved.So at this time there is no Protocol.

If you want a Protocol and the present situation is not acceptable to you,what Protocol do you propose?
Alan, I detailed it in my first reply to Rudeofus. Crank up the enlarger head and make relatively high magnification prints. The differences become plain to the eye, and you don't need to rely on high resolution scanning with all its artifacts. You can scan at screen resolution and clearly compare the prominence of grain.
