Just be aware that the stated capacities of the kits differ, and that their exhaustion rates will likewise not match. So that table of times won't necessarily help you much.
If you have a densitometer you could put a test-strip in with each batch to track the developer's performance.
Funnily enough I do have a densitometer but have only used it for B&W film. I will research using it for colour.
I did some C-41 processing a couple of weeks ago - got through two rolls of 35mm, about eight of 120 and half a dozen sheets of 4x5. By chance I had two very similar exposures of 4x5 so I had one sheet done by a good quality dip and dunk pro lab as a reference for my processing. As can be seen they are close enough to identical. The processing was simple enough, although a bit frantic with the primitive method of temperature stability (hot water in a 20 liter tank.) Looks like I'll be teaming up with a friend to split the cost of a 5L Jobo liquid kit for the next phase.
Well done mike :-)
