Thanks Man in Two,
I think we are talking about the same thing and there is nothing to be sorry for.
You are talking about how it is laid out or "made" essentially and though I am glad you shared the math, I already knew it.
I was talking more about the applications because I have heard many people using the term "follow" and I simply did not not what they meant by that.
But both you and Mario have each given me invaluable insights in two different ways, and I appreciate that.
Thank you very much.
