Asked: At one length, one coil exhibits

reduce the coil length, what length for the SAME coil would that be
to render
Vf = 0.2
for instance?

Well, let's help Cecil navigate this with his MENSA walker.

First, myopic translations of SAME coil are bound to confuse him into
thinking that this means the coil was never shortened. We'll put a
bullet into that suffering idea right now - the coil is shorter.

Investigating Fig. 1 reveals there is no way to resolve the Vf through
shortening a coil. Only Cecil could argue there's a pony in all that
horse****, so while he's saddling himself to that mound, let's proceed
to see why his dotaged enthusiasm is ill-founded.

Fig. 1 is based upon the formula (32). Nowhere in that formula is
there a turns. Turns may be found, but the specification, s, is for
pitch. Pitch for any coil remains the same irrespective of its
length. Frequency does not change, diameter does not change; it then
follows that Vf does not change when a coil is shortened.

So, the short answer that eludes Cecil is that the question above (or
its variants) has no other answer than the one value already provided.
By reductio ad absurdum, any kink in a wire that describes an arc of a
helix with a large D for a small s; and Cecil would impose his curious
theory's delay based on his poor reading skills on Corum².
