I've done some rain-forest hiking, and I've noticed similar results. If you really want to see some wandering tracks, try hiking along the base of some cliffs, in dense forest.
I have noticed that the errors do seems to be less the faster I'm moving. If I stand in one place for a while, the path can wander over quite an area if there is dense cover. If I walk fairly quickly, then it still has errors, but not as large. I think it must be finding more open patches and correcting itself more often.
