The same trend is observed. At this very high latitude, the sec LAT correction factor is about 4. The error triangles are hugging their assumed longitudes and the large correction factor moves them close to the correct position. This is the largest error we have seen so far, and is probably magnified by the large correction factor at the distorted extremes of the map.
I should also point out for this position, we are in TZ +00 with a BTZ of +00, and therefore the screen clock reads GMT directly.
