Optimal compost substrate composition Q, ???

This technical Q is respectfully directed at Anno & others of vast demonstated mycological expertice (You know who you are).
While nothing is perfect. In general, what would be a "near optimal " specification for an organic (aerobically made) compost substrate specificaly designed for the cultivation of general non/specific P.C. strains?
Please consider cost, material availability & labor factors, so that the specification is economicly feasible to produce, in bulk.
As an example:
pH: 7.0 - 7.5
Soluble salts: 3.0-5. 0dS/m
Carbon Nitrogen ratio: <25:1
Total nitrogen: 0.8-1.5%
Available ammonium: <10ppm
Total phosphorus: 0.2-0.5%
Total potassium: 1.5-2.5%
Total calcium: 1.5-2.5%
Total boron: <25ppm
Available boron: 1ppm
Lig: 3.1%
Cellulose: 12%
Hemicellulose: 13%
Microbial diversity Index: >8.
Moisture content: 50-55%
~~~~~~~~~~~~~~~~~~~~~~~~~
At oner time a FOAF of the Raccoon's attempted to formulate a shreaded wheat straw/dung material & pelletize it for the purpose of using as a semi/pasturized readily available (easy to use) substrate.
That was not a failure. However, the cost of labor, material, equiptment & variables made the product to expensive for mass production. Going back to the "drawing" board, it "seem's" a more feasible route is to simply make a stable organic compost specificly designed as a nonspecific mushroom substrate.
Any info and/or points in the right direction would be greatly appreciated.

Hmm...one compost formula can be found here, but I?m not sure if that?s what you are looking for:

Anno, Thank you for the reply.
Sorry to say, I'm not looking for a formula to make mushroom compost. What I'm looking for is the optimal mushroom nutrient content of a perfect as possible P.C. mushroom compost, after it is made.
As in the example I started this thread with. Do you think that is close?
I suppose there is not much published info on the optimal nutient, mineral, cellulose & microbe content of any manufactured mushroom compost. As all composts start with differing material, treatment, turning time, humidity & temp.
But, there must be some info of that type -- somewhere?
I have done several hours of web searching, and found nothing diffinative - yet.
SixTango -- still trying
