    Hi!
    Top one: Last dist dinguishable one is 16 + 3*2 = 22
    Bottom strip: Last distingishable one is 1 - 3*2 = -5

    22 + (-5) = 27
    27 / 3 = 9

    ;-))

    The Argument is: If you underexpose 2 stops, you can still distingish on
    the dark side to "16" in units of third stops. If you use the same
    target and overexpose by two stops, you can still distinguish to "1" in
    the same units. So "16" was really "22" for normal exposure, only that
    your monitor/eye does not see the difference above "B" = 16. On the
    highlight side, the target does not provide further logarithmic steps
    between "A"="0" and "1". These are filled in by the over-exposure trick
    and reveal that the camera can still distinguish 5/3 more f-stops in there.

    Hello! Did you read the note under the image? The adjusted numbers?

    The range is -5 to 24, at a minimum.
