I may have been wrong about the 18 rolls, though, as I recall something about up to 60 rolls per liter of concentrate.

Thanks for the answer. I guess that the 4 rolls no multiplier rule is in the case you make 1 liter stock solution (1+4). I would love 1+6 one shot but then times can be extremely long for gamma=0.7 (I need it because I am using a color enlarger). I have not found the datas in the leaflet from the box
