Photo Engineer (Ron Mowrey) isn't a "self professed" expert.self professed experts on the internet
He is a chemical engineer with a high level of expertise in the real world (outside the internet) and decades of experience with designing and refining C41 films and C41 processes.
And while he is retired from Kodak, he maintains regular contact with people within Kodak who still do that type of work.
Most likely, when used in a washless procedure, the Bellini chemicals give results similar to the results from other washless products - including the ones offered by Kodak. Those products and processes are what the realities of the minilab market requires.
That doesn't mean those results are optimum.
I note that the Bellini website has separate product categories for Professional labs, minilabs and amateur products. If you compare the products listed thereon, you will note that the "minilab" products list refers to a "stabilizer and chemical wash" whereas the "professional" products list refers to a different product - a "stabilizer".
