With the dials at the GUI, this human error factor is factored in.
But it's possible to make a complete almanac for the years of war.
FORMULAS:
All values are calculated with formulas (hight of the sun etc.). This is essential to get the azimut (A) and the Radialversatz (u); without them you can't determine your position. Examples of the formulas will follow soon (it's a lot of stuff).

Each will allow you to calculate the offered data for almost any date or time including our area of interest, 1939 thru 1945.
