t'=t/((1-fi)^(1/3)) is the correct value. However, the expected time
dilation is based on the same values on the surface of Earth. Since
the basis is the far away from the masses, the difference turns out to
be about 1%, when you equal the values for the surface as the basis.

Where is the *math* that shows this?

And does the formula then predict a better agreement for an object in
low earth orbit?
