So let me repeat my earlier questions.

I previously answered your question in capital letters.

What went wrong? Why is that number incorrect?

This is about the 20th time that I have explained the error
that W8JI made. The signal he used to measure phase shift
didn't possess a phase shift. W7EL made the same mistake in
his "delay through a loading coil" measurements. When the
phase of the total current changes hardly at all from one
end of a 1/2WL dipole to the other, that current CANNOT even
be used to measure the delay through the wire. Why do you,
W8JI, and W7EL think a current with an essentially unchanging
phase can be used to measure phase shift? This is all explained
on my web page.
