    I assume that this means that who ever supplied the dev times did not supply the information. In this case, I usually assume that they rated the film at box speed or try to cross refereence with other published data (or, ask here ). In anycase, all published dev times should be considered rough starting points which you refine to your own conditions, processing techniques, etc...

    Yes that seems to be the case.
