Umm, while interesting, it would be nice to know the speed comparisons and contrast values for the films. Otherwise we don't know what the actual data represents. These are just points of data hanging out to look at.
To be a fair comparison, all films should be developed to the same contrast and to the rated speed in a common developer.
In addition, use the same test target for each film and then put the same areas of the target under the microscope.
For up from the ashes, up from the ashes, grow the roses of success!
I dont want to have scatches by any clamps or whatever. If you look closely you will see on some images that the corners are somehow out of focus because the film is not fully flat. I just try to stay in the center of the film-strip so I only have light bending and not an angled surface like I would get on the curled edges.

Ilford Delta3200 (@ ISO3200) in Rodinal 1:50 at two spots with low and medium density on the negative
The second one is - according to some people around - not an optimum combination. But I tried it once and now I can show it here.
A Rollei 80S (planned for SD2525) and a Fomapan400 (planned for Rodinal) are in my camera right now. So these will be the next ones shown here.
so ... fire away
PS: Just some remarks on my development process: All development is done in a Jobo drum by hand with tilting. Developer (in aqua dest.) tempered with an analog thermometer. Chemistry measured with small measurement cylinders. The time is taken from a stopwatch.
