You are the expert on Vf. You assert without proof that a half-length

accepted that supposition, what happens at a quarter-length or at a
tenth-length? I am simply asking how the function changes between the
"known" limits of 1.0 and 0.02. You have repeatedly ducked any sort of
answer.

Seems Richard Clark has proven that it doesn't change between
the "known" limits of 1.0 and 0.02. Where did those "known"
limits come from anyway?

For a single turn coil, seems the VF would roughly be the pitch
divided by the circumference, something that would equal 1.0 only
when the pitch and circumference were equal.

For the 4 TPI, 6" diameter coil, the VF formula yields 0.02.

The pitch divided by the circumference yields 0.013.
