I don't use the SM chemistry, but with the Flexicolor Developer / Replenisher (http://www.adorama.com/KKFCDR5G.html) I just use the stuff at the minimum amount needed for the Jobo. So that comes out to about 135ml per roll (270ml in a two roll tank). I do not replenish, or reuse, the developer when used in this way. I reuse the bleach one time. And fix is also one shot.
