I haven't reached that point with my current Cinestill kit (it's at 7 rolls now, Cinestill recommends compensation after 8), but may not reach it, because the developer was mixed in early April and is already a month past the "deadline" for using it. I'll probably use it for one more roll (XP2 Super, so at least I don't have to worry about color issues -- it'll develop, or it won't), and then reexamine whether to continue with kits, return to mixing my own (developer and bleach, the fixer doesn't seem hard to come by and is cheap), or source bulk quantities of Flexicolor ($$$ and more $$$ for shipping of gallons of liquid) and start replenishment.
