If we are going to split hairs then:

The error from the theoretical parallels would vary both with altitude
and location on the globe.
A geodesic error will cause different errors on the two strings as the
earth is not a perfect sphere.

Not only that, but you would certainly need to do gravity meter surveys to
insure that the gravity field is equivalent at both locations prior to
embarking upon any calculations.

You can't be too careful ...

assuming you can freeze the measuments in time so not to be exposed to
planetary rotational pendulum forces which ALL plumbobs have a problem
with. The farking things just never hold still. I understand bourbon
has a stabilizing influence on planetary rotational sidewalk-in-the-
faceness.

Say what?
