That's the nice thing about this approach compared to the draw your own circle approach. As Ken mentioned, the tricky part is dividing up the points around the hand-drawn circle. A printed compass rose at least gives you a reliable starting point.
And:
"6.Multiply that ratio by 22.50*(degree)"
That's a typo, I assume (it was in Jim's post, too). It should be 23.5 degrees.
