Huh, learn to proof read. Also see if you can find out the difference between mathematics, arithmetic,
trigonometry and geometry.

So if you have a compass with 40 degrees of error, (large but not unheard of), and you
"align" your RDF (which being assembled by you from a kit from Heathkit) has an error of
40 degrees, you could be of by 400 degrees? Astounding Jax, simply astounding.

oh? errors don't multiply?


In this case that is correct.
