Help with Parodinal concentrate

Hellos Guys and Girls. It´s been a few days since I made Parodinal and now I need some help. I want to develop up to 10 films at same time on a Jobo tank and I´m not sure what concentration should I use. I don´t want it to be exausted before the films be complete developed. So my thoughts are:

5 ml of Parodinal for each 120 film ==> 10 films ==> 50 ml of Parodinal.

2 liters to cover half of the reels ==> concentration 1:40.

What are your thougths? Does it worth a try?

Anyone?... Please?

i have used parodinal at 1:50 for 16 minutes 20C. one full minute of slow inversions then 3 inversions at 4, 8, and 12 minute mark. i was photographing in snow so the concentration was good for getting good highlights and very close to box speed. i have experienced that parodinal is prone to fogging as time increases so i tend to keep times under 20 min. i'm developing for diffusion. hope this helps.

I think that would be o.k. People use it (and actual Rodinal) at much lower concentrations.

Thank you, guys. Helped a lot.

Anyone have experience developing 10 films all together?

i wouldn't do 10 rolls together with a developer i barely knew. do the first roll and adjust your times from there. seriously.

Thanks. Some friends told me the same.
