You're welcome. I always felt like I was just getting a piece of how depositors worked. This started off as a labor to understand them and turned into an article. Everything I read, never gave a clue where to start in creating a chain. Finally it hit me, just start with each placement. I didn't put it in the article, but I think the "tree" came from handwriting it out before we had computers or typed out our information. I can't verify this, but it is my hunch based on that you wouldn't want to write all over the chart itself.
