I agree. I wasn’t suggesting this to replace C41.
And in practically every instance I would prefer to have my color film developed in the proper C41 chemicals using the Kodak specified times, temperature, and techniques. I plan on continuing to develop my color films almost exclusively in C41.

I’ve shot Fuji 800 at ISO 3200 and was very satisfied with the results from this ‘developer’, more so than pushing with C41. I am not sure of it, but I believe that with this home brew you gain film speed and easier control of contrast and density. I think it does well with Fuji 200 and Kodak 400. With that in mind, it might be of interest to those that shoot XP2.
