Three inches out of 100 feet also requires an accuracy of 0.3 inches for
a plumb bob string hung from a 10 foot section of tower.
Three inches out of 100 feet calculates out to be a total angle of 0.14
degrees. By that criteria, the 0.1 degree resolution of the digital
angle gauge I used doesn't seem like that much overkill. I guess I'm
just one of the particular ones ...
