Hello, Kuortam. Since you asked within the discussion instead via PM (I'm glad I read this thread today), I'll put my notes here for you and any others who might be interested. In the old thread that you've included a link to in your post #943, the dead link was something posted by the Film Ferrania people, not me, so I don't have that dead link info. But if you want to know how I developed my P30 in 510 Pyro, here are my notes.
4 April 2018
Develop approx 24 exposures of new Ferrania P30 rated at ISO 80 with Olympus Pen (original) half frame then with Nikon FE2 w/ various lenses. Spectra-Combi incident metering for Olympus, in-camera metering for the FE2 for the most part. At home.
Develop in 510 Pyro at 22C, 3ml in 280ml water (I used a bit less water because i may have not gotten the full 3ml into the main mix). 12 min total, initial agitation for first 30 seconds, then point in the cardinal directions every 30 seconds until 9 minute mark, then invert every 30 sec to 12 minutes. Combina small 35mm tank.
Water stop bath, then PF TF-5 Fixer 6 minutes (10th use) constant agitation. Rinse, HCA for two minutes constant agitation. Running water 10-15 minutes. LFN and PhotoFlo in tap water, then hang to dry after see-sawing film through tank.
Results: If the initial scan of the negatives in sleeve is anything to go by, the exposures and development appears to be very good.
