For those of you that use very little C-41 and are into compounding their own developers in the Nov/Dec 1995 Phototechniques magazine has an article by Patrick D. Dignan. Its title is "Dignan NCF-41 A divided developer that works" It is about a divided developer with A and B baths. The batths are kep seperate. The developer has unlimited shelf life. It is used at 75ºF.

BATH A MUST NEVER BE CONTAMINATED WITH BATH B
No prewet should be used.
An Acetic acid stopbath is used.
The bleach at 75ºF will be much slower. Film can stay in the bleach for 1/2 hour w/o a problem The film can not be over bleached. Remeber that the bleach is meant to remove 100% of the silver so over bleaching can not happen. It is entirely possible to under bleach.
I have not tried this formula myself.
For those of you not familar with his name Mr. Dignan has been known for a longtime in the photographic industry and is highly respected.
This is said to be a very inexpensive developr.
