Don't know of any official engineered way to handle different height guy
anchors. For mine where that was an issue I just calculated how far out it
would be to keep the same angle at the tower to each anchor point. I don't
know that it really matters that much unless there is a huge difference in
the height of the anchors as the tension on the guy wires only varies a
small amount for those types of differences.... and for 80' of 55g I'm sure
it will make no difference at all in what it can handle for wind load.

I don't see how it is possible for the angles to be the same - not
mentioned, but I'm doing as I think most do, which is one anchor point per
pair of guys.
I can keep the angle of the top set of guys to the tower consistent for all
angles, but that would put the anchor point at different distances,
depending on whether those anchors are above or below the level of the base.
That's easy enough to do, but then the angle of the lower sets of guys would
differ.
And that is the question - what is the most important? To keep the angle of
the top set of guys consistent? Bottom set of guys? If the guys are split
between two anchors per pair of guys, wouldn't the guy wires potentially
cross when keeping the upper and lower angles the same?
My initial plan was to just make sure that the angle from any guy wire was
not less than what it would be if I was guying at 80% on level land.
