Vikings get cranky when they haven't looted, pillaged or slain a dragon recently. Despite my Norske and Min roots, I find living by the beach in California to be a superior choice.

I just did some testing with Fuji's Green Sensitive X-ray film. (I'll write in the exact name later. The box is at another location.)
I exposed a white card at Zone VIII using a Pentax Digital Meter. I rated the film at EI 50. The lens had a Hoya X1 filter on it, a light yellow green. I didnt' make any adjustments for the filter, as I always plan on using one for landscapes.
I exposed a black card on Zone I.
The films were developed in a Jobo CPP-2 using an Expert drum at 75F. The first minute the rotation speed was set to 4. After that, the speed was adjusted to the lowest possible setting.
The film was developed in 1 Liter of Pyrocat MC in glycol for 6 minutes and 30 seconds at the standard 1+1+100 ratios. (The film was drained with 30 seconds left to go.)
With both emulsions in place, the film base plus fog was .23 in both ortho and UV mode. The zone I card gave a density of .33 (ortho) and .38 (UV). The Zone VIII card gave densities of 1.88 (ortho) and 2.28 (UV).
After stripping the back emulsion, the readings were FB+F = .17, Zone I .28 (ortho) and .32 (UV). Th Zone VIII card gave 1.10 (ortho) and 1.31 (UV)
For scanning and silver printing, I prefer a Zone I density of about .15 above FB+F and a Zone VIII density of about 1.30 above FB+F. As a result, I'm going to try developing for 8 minutes.
Peter, thanks for posting your very detailed experiments and readings! I have shot a lot of the green stuff and developed in Rodinal, but I want to try it in Pyrocat instead, so I will use your starting point of 8 minutes when I get around to shooting some more 8x10 one of these days.
I have been working with X-ray film for only a month or so. I purchased 100 sheets of Fuji HR-U size 7 x 17 mainly since I just finished restoring my Kodak 7x11 camera and had not film. I felt it would be better to cut 5x7 to start. Here is an example of a trip to North Carolina Stone Mountain State Park. I still have work to do, but so far some shots are OK.

You can see two marks/scratches on the top and two on the bottom where the MOD54 was holding the film. Not sure how to prevent that. Easy enough to heal in Photoshop. Just too lazy last night.
