Quite.
You thought this was a Newtonian derivation of the prediction
for the Shapiro delay:

You believed that Newton could predict what you called

Which means that you now have accepted that Shapiro's

What you were not aware of is that the equation in
the attachment is the GR prediction, and _not_ the Newtonian
prediction. So the figure in the attachment shows a perfect
fit between the GR prediction and Shapiro's measurements.

The point is that Stephan Gift's paper

is nonsense.

Gift has "stolen" the equation and figure from Pössel
and has done some mathemagic to make it seem that
the equation is the Newtonian prediction, which it is not.

This is the paper with the correct Newtonian prediction:

Note that the equation you call "1971 Shapiro's formula"
is equation (27) in this paper.
Quote:
"Formulas (17) and (19) for one-way travel, corrected by
the multiplication of the delay term with an overall factor
2 to go from the Newtonian to the general-relativistic result,
Δt = (2GM/c³)⋅ln((r_E+x_E)/(rₚ-xₚ)) (27).

So equation (27) is the GR prediction.

Your figure (2) is FIG.6 in this paper.
It is Pössel who has drawn this figure with the GR prediction
equation (27) and measurements from: Irwin I. Shapiro et al.,
"Fourth Test of General Relativity: New Radar Result,"

To go from the Newtonian prediction to the GR prediction
by multiplication by two is Pössel's idea:

Quote:
"Begin by presenting the simplified derivation developed in this
section. This will yield a result that has the correct functional
dependence on the geometry, but is off by an overall factor 2.
Give the students the additional information that a more thorough
derivation, which includes the curvature of space, will yield a
result that has an additional factor 2. After that statement, you
can use the corrected formula, with the extra factor of 2, to
consider applications such as the ones presented in section V,
where the Shapiro time delay formula is used to compare predictions
with data."

So sorry, Richard, you have yet again made a fool of yourself.

But at least you have finally accepted that Shapiro's
measurements of the delay were correct, and no HOAX.
