Afraid that I just don't understand! Would any of you with a new Ford automobile, expect Chevrolet to answer you if you asked Chevy how to set the "Ford" clock", I think not, but I may be wrong with some in this group. Ilford, in my opinion, is under no obligation to supply you with information about developing any of their films in anyone else's developer. The fact that they do so has a lot to say about their ethics. The same, of course, applies to Kodak as well as others. To me, this seems "unique" to this industry, so let us cut Ilford, Kodak and others some slack, as folks say.........Regards!
