Of course it is shown. Draw a vertical line at 10^-3.
The 10k turns per lamda coil

Well, in fact it does not (and nothing shown on the graph along that
ordinal line does).
What happened should be obvious. I correctly used the 10^-3
vertical line for the first one and accidentally used the 0.01 vertical
line for the second one.
The first observation is OK. The second should be changed to
500 turns per lamda with a VF of 0.96.
The same principle still applies. As the turns/lamda increases,
the VF decreases while keeping the diameter and frequency
the same.
