guy stood at the base looking up the tower while 3 others adjusted the
turnbuckles at the guy anchors to get it approximately straight and
vertical. Once it looked OK, each one tightened his turnbuckle by the same
number of turns until the guy tension (measured with a Loos Gauge) was
correct.

Well, the vertical tolerance spec per the TIA-222 is 3" per hundred
feet. Some people are just more particular than others.
