| 415 * 360 degrees * 60 arc minutes * 60 arc seconds =

It doesn't matter, I deliberately chose an odd number to
cook the results and 415 happens to be the number of
orbits Mercury makes as Earth makes a hundred. I laughed
because you are doing much the same thing with your
gravitational lensing of light. Orbits are known to be
chaotic and there is no analytical solution to the three
body problem. If GR could do it then mathematicians
would be delighted. A nice model exists he

Of particular interest is example 8, a full orbit is completed
before the system degrades.

What with Jupiter, Earth (and its Moon) and Venus pulling
on Mercury it is quite impossible to analytically prophecy
where its perihelion will be 100 years from now, whatever
the prophet Einstein and his disciples predict. Blind faith
in the holy shaman has been with us since the pyramids and
Stonehenge were built, these neanderthals such as Fecal Jeckyl
of today are no different to their ancestors. In a different
society and a different age they'd be consulting the Oracle
at Delphi.
