If I'm doing a Newtonian calculation, I do it with Newtonian
physics.

Whatever it does (and I have no interest in your nonsense),
the result is not Newtonian physics. Call it something else.
If you want to ask, "what does pure Newtonian physics predict"
then the answer is done with Newtonian physics, not some
hybrid.
