Does that mean the maths is correct for the right or
wrong reason?

It means the maths is right, period.

The maths might be right.

Yes Henry, the maths IS right, not "at least 20% out" as
you claimed above.

After all its predictions are exactly the same as the
BaTh in most cases.

Nope, most are completely different and ballistic
theory gets them wrong. Sagnac, Shapiro, the GPS
accuracy, pulsars, contact binaries and so on all
get incorrect predictions using ballistic theory and
your excuses that 'something else is not being taken
into account' doesn't solve that problem. Using SR or
GR gives correct answers which is all anyone cares
about.

But why make a simple process appear incredibly difficult?

Simple answer: it's the only maths that gives the right
answers. It isn't that difficult in theory, the ultimate
equation is just one line:

How simple is that? It is the solutions of that equation
that are the hard part, but only because humans haven't
evolved with maths co-processors in our brains.

The reason it is used is because it covers a topic that
ballistic theory doesn't address, GR is primarily a model
for gravity and it is far better than Newton's.

Oh crap. It doesn't tell us anything about gravity.
It merely describes how space would have to be distorted IF light speed was
constant in a gravity well.

The only
other mathematical alternatives not already falsified are
limited in scope to regions where they are indistinguishable
from GR, and in any conditions where a testable difference
occurs, GR has been shown to be the one that is correct.
Look up MOND if you are interested. Both SR and
Newtonian gravity can be derived as asymptotic limits
of GR and SR merged with QM gives QED which predicts
everything about light and its interaction with matter with
incredible accuracy.

Bottom line? GR and QED work, the alternatives don't.

The true alternatives haven't been correctly applied.
