Jobo has a page on it, and if you read it carefully, it says you need 200ml of full strength developer per roll. They also go on to say that as little as 140ml per roll works with some Kodak films. http://www.jobo-usa.com/jobofoto/bulletins/xtol.htm What this means is with 1:3 dilution, to do one film, you should add at least 560ml of diluted solution, or 600ml if you use the 200ml per film figure. This is too much solution for the jobo tanks, where a one reel tank take 140ml, a two reel 260ml, and a three reel tank combo taking 470ml. I guess you could do one roll in the four reel tank that takes 590ml. As you see, dilutions and Jobo's can be complicated. Using an eight reel tank, you may be able to develop two rolls of film! This is all fine, if you have the larger tanks, but limiting if all you have is the 260ml, two roll tank. I tend to use Xtol undiluted with the jobo. I have since gotten the larger tanks and may try it 1:1.
