I've just had an awkward sim session with a seasoned trainer completely at odds with everything I've been taught about RVRs at my previous gig and not a single legal document exists to clarify the disparity. What a stupid stupid position we find ourselves in in the year 2018.
My airline incorporated such a table into the QRH. For Cat III, it explicitly includes "Any one RVR may be temporarily inoperative"
Maybe the "seasoned trainer" needs to check with the standards people and find out their source documents for the new procedures...
