I have never denied that it provide such an advantage. I just don't think that it is is a very significant one, at least in the big scheme of things. Wind, after all, is the true enemy, not lack of routes for which the elevation is known (note that I did not say "flat", since that is not a requirement when using either the signal averaging or regression approaches).
