Tall buildings aren't guyed structures, Bill. I wouldn't expect to
see 1"/100' deflection
in a guyed tower, unless the guys weren't properly tensioned. To
follow your rule,
you'd see 20"-40" side-sway at the top of that tower. I don't think
so.
I've been on self-supporters-- you can feel the Tour Eiffel sway in
the wind, slightly.
The highest I've climbed on a guyed tower was 190', and it was as
solid as a rock,
even with 30kt winds gusting.
Having said that, I would imagine that you could measure some lateral
deflection in
the top of the 2000' tower, with wind gusts. But I doubt it's
enough to actually feel.

That what the "Engineer" said not the tech who does the work :) the
spec
from rohn is about 1-2 inches of movement (if I recall correctly) for
each
100ft at the top. Even tall buildings move with the wind. I am
sure you
can feel movement at the top of that 2000ft tower.
