Suppose we have two films that are stated to be of the same speed. Assume that the
developer, dilutions, temperature, agitation procedure, etc. used by the manufacturer
in determining film speed are identical for the films.
Question: What, if anything, can be inferred from the difference in the standard
developing time suggested for the films by the manufacturer? (Of course, for the same
developer, dilution etc.)
