With Tmax RS, I need about 35ml of concentrate per 8x10 or equivalent to be sure I do not exhaust the developer...... Xtol will have a similar requirement ( a minimum developer to stay away from exhaustion) as will D76, D23, or any other joy juice you like..... Some developers are more active, and require less concentrate per roll... others are less so and require more concentrate.. It depends.... Thye problem with the JOBO, and especially the CPE2 is that the motor is only so strong.. and therefore the maximum chremistry per run is 600ml.... so the requirement for developer activity, dilution and maximum volume get in the way of each other.... Bottom line is that you may, depending on the specific developer and dilution you use, may be able to put only 1, 2, or 3 rolls of film through 1 run.
