Where is the transition in Vf from the ~1 for zero
turns to ~0.02 for a resonant coil?

Take the VF=0.02 resonant coil and divide it into two equal
coils. Do you really expect the two coils to have VFs of 1.0
while their end-to-end combination results in a VF of
0.02? Please quote the laws of physics that allows such
to happen.
