Thanks, I didn't know most of that.

Still, there is scope for variability in things like replenishment rates 
altering halide content, water quality (I assume the Kodalk content is left as 
a variable to deal with this), and (from my tests and experience with B&W) 
agitation techniques and frequency. The latter has a profound effect on
grain. A belt transport minilab, deep tank with burst or dip/dunk, and DIY 
one-shot processing seem unlikely to give the same results from nominally 
identical chemistry AFAICS.
