If you had any idea of what you were talking about,
you would know that the total phase shift is unrelated
to the total delay. Some incremental phase shifts are
related to the velocity factor. Some incremental phase
shifts are instantaneous. If you don't already know
that, you don't know how to use a Smith Chart.
