I am the OP, so it was my fantasy not @dover .
It is not “tangency”, but the walking of the point across the platter dues the arc of the tone arm.
But as was pointed out in the very opening post it amounts to “a bee’s phallus” amount of shift… I used the term, “it is not much”.
(Where “Bee’s _ick” is the Australian slang term for “a small and almost immeasurable amount”. I believe that the UK uses the acronym of “SFA”.)
My main claim was that I found it “somewhat interesting”.
What is more interesting now, is that we do not agree whether it is truely happening, or just a fantasy.
And also that my communication likely uses a lot of body language and hand motion to describe physical things.
