I am really glad that I posted the original question. I was hesitant, since I had just started the LP (Maybe the answer would reveal itself as I continued to work? Did I miss the explanation on this in the book?), and was pretty sure the question had been asked and answered somewhere else in the forums. I was dreading the "follow this link to the answer; this question has been asked and answered."
The explanation that followed is/was super helpful and informative. Thanks again.
