Please write complete ideas. May be right about 19.5 degrees? You are the one who said
"I said in my eariler post in similar words that my view is that in regard to Pensylvania Avenue that begins at 23.5 degrees to the White House, and from the White House alters to 19.5 degrees,"
You have described it as 19.5 yet label it 21 because that is what it measured in that map? I'm not sure why ypu don't see this as a conceptual problem- the fact that your label doesn't match your illustration.
"Bigbytes, I am trying to go beyond these discrepancies. Its clear to anyone that the image is there in the map. What I would like to discuss is the meaning of this image; what is it really telling us?"
What image is it that you describe here- an altered version of figure 6?
Why don't you fill us in on what that image is telling us.
Please do me a favor and make yourself a drawing where you connect all the points of the pentagram, then look at the right side of the triangle.
