Arguably an even better way to do it would be to imagine super-tall

It would seem that this would subtract coriolis and centrifugal
inertial
effects from your g value. Are not these effects part of the chosen
frame?

It depends on what you mean by "the" chosen frame. One of the main

here is the existence of a multiplicity of inequivalent frames that

reasonably be chosen.

I understand. I was confused with your statement because I thought that
the frame had already been chosen to be an "earth surface frame", so that
these options had been thereby specified.
