    I'm learning as I go so please forgive any stupid questions.
    The Manual J 8th Edition gives the Runout cfm, Runout duct size and the number of Runouts for each room. Are these values considered Manual D numbers?

    I suspect you are using a software package. The software package may be making suggestions based on manual J and Manual D.
