Hi,

I teach wildrness survival here in Sweden, and this caught my attention. I have been looking at this -- a bit unstructured, but that may change -- and also noted just a couple of days ago that the "horizon" intercept was something like 150-160 degrees. For serious navigation an error of 25-30 deg. is obviously way, way off. But in a survival situation you often only need a "close enought" direction. Example: a man out fishing gets lost in the woods, and spends 10 days wandering around before meeting some canoesists. He was south of a major road, but unfortunately kept moving mostly southwards. If he instead had gone mostly north (+/- 30 deg would be fine) he could have ibeen back hone before the night was over (summer in mid-Scandinavia, so not dark). So I tell students that  it is not perfect, but never let perfect keep you from doing good enough.
