I believe I started the thread you are referring to and I have since tried it with Fuji CAII paper as well as Endura and found that by lowering the carbonate to 30 grams no pH adjustment is necessary (keep sulfite at .2 grams) and it works well with both papers, normal contrast with no crossover. In fact, I normally prefer it over the Kodak RA-RT developer, although I still use both. Use at 68 F for two minutes. Mix with distilled water. I don't know how it will perform at high temperatures. Contrast can be controlled by altering the amount of carbonate but watch for crossover. It is odor free but has a life of only days. I mix it as I need it. Also, it has no tar preventing chemicals so expect a little build-up. Most can be removed with alcohol.
