Thanks for all your posts. They have all been helpful.
I agree, put the plotter in line with the compass rose and off you go.
BTW the errror is more noticeable on the 1/4 mil chart. I did, however, assume that by lining the plotter that way, or adding the variation, or reading the radial of the chart or whatever, that they would all produce the "exact" same result (in theory).
I'm obviously too pedantic
