Your numbers are more along the lines of what I expected. Maybe I should
run my numbers through the Plotter program myself so I'll understand this
better. I tried to use the old Mac version today but I couldn't get it to
work. Is there any way I can judge the ISOs myself based on the curves I
got back? I think there is a little triangle thing that you make and
place on the curves in a certain way, and then you put a ruler under the
curves and draw lines down to the ruler and find your ISO that way?
