No, the difference between (1-2fi)^-1/2 and (1-fi)^-3/2 is not
1%, it is 50%. Expand the two functions out in a taylor series.


Sorry, I made a typing error, but you used a third value....

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.
