This makes no sense to me. Every film manufacturer suggests additional development time for every 80 sq inches of film. One roll of 36 exp 35mm = 80 sq inches. 4 sheets of 4x5 = 80 sq inches. You're exhausting your developer every time yo process a piece of film. Regardless of what sort or amount of precipitate there is, the strength of the developing agents is reduced with every use, so, it would seem that developing times shouldn't remain constant in order to maintain consistent results.
Let me see if I understand your process. You mix a gallon of WORKING solution, i.e., stock solution diluted 1:1. You then use some of it to process your film, and dump the used and partially exhausted developer back into the jug of working solution. You then use this very same working solution to process more film, again dumping the used (and further exhausted and diluted) developer to process more film. You repeat this process through ten sessions, never adjusting development. Is this correct?
