Doremus, thank you for your kind observations, I appreciate them. I don't find that compounding my own developer, or fixer, takes much time at all. As ammonium thiosulfate is a liquid, I find it is, actually, a very fast procedure. Further, it is not taking an awful lot of my time and effort. I do it, because I do enjoy this part of photography, albeit not as much as the creative part. Besides, I have a strong scientific background and I have always liked to question things till I understood them. I fully appreciate your points about Haist and others having done this work professionally, but it has been a while since things have progressed, since those days. I am sure there are improvements that can be made, and if no one asks questions, not much is likely to happen. Even because of Ryuji's, and Mark Overton's work, we have those new options, that did not exist a few years ago.
So, even if it did not apply to my practical desire to improve my existing process, which is very similar to yours, I would still like to understand the impact of sodium sulfite on archival/optimum fixer capacity, or of ammonium thiosulfate in KRST on the same, and about good buffers for a neutral fixer, so as to be even better to the process, results, and the environment. Besides, I find photochemistry, just like the tone reproduction process, truly fascinating, and I yearn to understand the logic behind them, as much as I am able to.
