RE: Navigating by the Stars
I suppose that if one were in northern Canada chasing the pole about 40K might seem a big jump. What you will note in GB might be the same 1 degree fluctuation per decade experienced in any other portion of the world opposite the fluctuation.
It comes to simple trigonometry. A 40K movement 10,000K away is only a fraction of a degree where I stand.
I'll keep my compass and check it to the pole star on occasion.
