Thanks for providing the link. I am very familiar with these numbers provided by Jobo. However, be aware that these numbers are not provided by Kodak. These numbers are the capacity of Jobo drums. They are not the same as the capacity of Kodak C-41 chemicals. I believe Jobo also said to refer to chemical manufacturer's capacity specs to determine how much chemical to use for how many rolls of films. In Kodak tech pub Z131 it specifically says 1 liter for one roll of 220 negative (4 - 5 rolls per gallon) on table 3-3 page 3-5.
