Ed,

I believe its important that we all speak the same language, and its
become apparent that the users of the reflector are confused about the
correct term to use to describe the angle from true north to magnetic
north.  Unfortunately you have added greatly to the confusion, not to the
understanding.

With all due respect, please provide the source for your statement that
"variation" is the correct term to describe the angle from true north to
magnetic north,

Here's mine:

The Engineering Handbook
Richard C. Dorf, Editor in Chief
IEEE Press
1995
Page 1563 paragraph 146.2

"The angle from true north to magnetic north is called magnetic
declination and is a function of the observer's location with respect to
the poles."
