According to Kodak Z131 table 33, the capacity of Kodak C41 developer is 4  5 rolls of 220 per gallon or 1 roll of 220 per liter. However, Jobo gives a capacity guide of 470 ml for 2 rolls of 220 (if I remember this correctly). I tried this Jobo capacity guide many times and I don't remember ever got a good negative. I wasted a lot of time to troubleshoot this in many ways but eventually concluded that the capacity of the developer is simply much lower than that. I now develop only one roll of 220 with something like 850 ml of developer. The result is always good. This is close to Kodak's table 33. I planned to try again with 500 ml to process a roll of 220. Haven't got the time to do it yet. I believe I have done this before and the result was poor. I will do it again to validate (or the opposite) the number in Kodak's table 33.
Kodak does not specifically recommend capacity numbers for rotary processing. It does say never replenish the developer in rotary processing. Table 33 is the capacity guide for general batch processing.
