OK. Sorry about the bad typing...clumsy brain/finger connection....so what would cause the gpsd daemon to mess this up so badly then? I don't need it here, but it would be nice to know for future reference as I've beat my head on the wall for near on two weeks now. Would it be worth a fudge correction and if so by how much? Half the average error about all the average error or just leave it alone?
