        I was reading something on this recently - from vague bits
        lodged in the grey matter :

        The IRE scale is in 10 segments, like the grey scale, So
        the basic thrust was that you could use it to "place" a
        reading on a particular zone by aligning EV reading against
        the IRE scale numbers. That is, if you measure a highlight
        you could use the 10 on the IRE as your setting, 1 for a 
        deepest tone - or somewhere in between. The IRE relates
        directly to your range zones/stops.

        Ah - it's in the Carl Shipman Pentax book. Above is correct.
        Just set your EV reading to your desired Zone on the IRE
        scale and you will have a direct relation of the zones from
        that placement. The pointer at the 3.4 on the IRE relates to
        "middle grey/average scene", but the scale can be used to
        "shift" towrds shadow or highlight favored exposures.

        My Shipman book is c. 1979 and covers MX - MESuper, 6x7, 
        K2/dmd/1000 and theAuto 110
