Sorry for my phraseology.

My question was directed to you because you made a 'distinction'
between Newton and Einstein but no one seems to be able to quantify it
OR qualify it.
It is all wishy-washy about the 'level of accuracy' you choose.

Quite honestly, considering the accuracy of calculations and
experimentation, I would have thought that it was clearly defined when
to use one or the other.

I'm not 'trying to be difficult' but it seems that it is a difficult
question for you to answer clearly.

My apologies.
