I offer to show results of my experiments with color developer dilution

Not all of us will use Kodak materials, so some of us will have to foray into alternative brands, Unicolor, Arista, Tetenol, and Compard/Rollie. But obviously that's our burden. I know that what is presented is the summation of many, many hours of work by the OP.
Here is what I'm seeing as a "cut to the chase" instructions for the C-41 part. I'm going to presume that one wants some volume of developer for one's tank, SS or plastic.:
1. Mix your developer of whatever brand to a stock solution.
2. Knowing how much developer you need for your tank, divide by 15.
3. Take that quantity of of developer and add some sodium carbonate at these ratios: For 1 liter, 3ml volume or a rounded half tsp. Of course, from there, lesser amounts or working developer, less carbonate. I know from my previous work in B&W, this isn't precision stuff. (The carbonate boost is a good catch by the OP for diluted developing.)
4. Follow advice for time/temp: 12-15 minutes with continuous or intermittent agitation at 90 degrees F, or 18 minutes at 180 degrees F, or 8 minutes at 100 degrees F.
I did like the discovery of the immateriality of bleach/fix sequence. I'll probably start doing a hard ammonium thiosulfate fix and follow with whatever blix I'm using.
Is that it? Did I miss or miscalculate anything?
Check your degrees and times... 180° at 18 minutes?
