I think Hrst said to have processed 2 rolls then reused the 300 ml for 2 more rolls. That's 4 rolls of 35 mm film.
I just did a quick browsing through all of Jobo's technical journals (24 issues). I could not find in any of them that mentioned about chemical capacity, including black and white, C-41 and E-6. I could find only in one issue that mentioned tank capacity (number of reels, rolls of film depending on format and chemical volume). I did not see any words that tell to use this much volume of whatever chemical for this many number of rolls of what film. Authors of these technical journals are all respected professionals. I could not find any of them addressing the subject of chemical capacity in connection with the use of a rotary processor.
I am willing to test again trying to figure it out. But I am not convinced at the moment that Jobo's tank capacity equals chemical capacity. Kodak Z-131 specifically says not to replenish and reuse developer for rotary processing. There must be some reasons that Kodak says this. I wonder if the same reasons cause any implication to the developer capacity associated with rotary processing.
I use Kodak C-41 chemicals only. Other brand of chemicals may have different capacity. Jobo ATL-2300 does not allow different volume of chemicals for different steps. I can use only same volume of developer, bleach and fix.
