Just some comments, wish I had some to play with.
First of all, great pics and details to everyone!
Seems to me that the lower ISO and lower agitation, to the point of stand development, is getting the best acutance, shadow detail and midtown separation. Highlights also control.
If it's rated at ISO80 and you shoot at 50, you overexpose highlights and maybe properly expose shadows. The low agitation or Rodial stand development acts as a highlight compensating factor, since the developer is quickly exhausted in those regions and not in the shadows. Lower agitation enhances the highlight compensating effect. The Rodial or R09 (if it's truly the same) gave the nicest images with d76 1:1 second.
If someone was really brave they could shoots some images of the silver halide grains, unexposed, with a scanning electron microscope. I am curious how they appear if they are more cubic or more flatter.
In any case, it's great that there is this kind of film available to work with in 2017.
I'll buy some and restart the film darkroom as soon as it's available.
