Hi Frank,
Interesting documen . While paging/scanning through it I noticed picture 3.4 "isogonic lines show same magnetic variation". This FAA publication is from 2011.
By coincidence, some weeks ago I downloaded a similar chart from the NOAA (https://www.ncei.noaa.gov/products/world-magnetic-model), for epoch 2020. It's interesting to see the change in magnetic variation over a period of approx 10 years. I put both charts together in attached document.
Regards,
Huub
