We all fly quite addicted along Magenta Lines, so charts have to be precise.
So, i.e. why are NOTAMS not shown correct in Skydemon? Example:

This 'Center' is not centered and maybe the planned flights corridor does not exist in reality!?
I realized the discrepancies when using a trial of ForeFlight Europe with the graphical NOTAMs update.
Taking some random NOTAM circles and inserting the center it seems Skydemon is sloppy in processing data.
Added this i.e. to the discussion on why they use rhumb lines instead of great circle and other behavior.
Decided I am out of Skydemon for now, too potentially dangerous for me flying.
I do like the charts representation clear structure, but cannot live with wrong data.
My 2 pennies.
Hmmm if you are using 51°53'00''N 0°16'00'' instead of 51.42'59''N 0°15'41''W it fits. I can see a pattern ;-)
It seems it's not better than 0.5NM at least for this type of shape.
Definetly not good. However I would sugget to keep clear more than 1NM of places where you should not be. You wouldn't fly that course with a 1:500.000 map either.
