I seem to recall that the instructions in the boxes indicated they were the settings when the time was between 10am and 2pm, when the light was basically flat and high in the sky. How do you estimate the light and apply the exposure setting at one hour before sunset? 45 minutes, 30 minutes, 10 minutes, 5 minutes, etc? There can be many stops difference during that period.
Did you have a look at the link John included?
