Thank you for this; lots of details, references and detailed diagrams!

One small note - the first image you mention that we'll need to reference is a bit small to read. Zooming in on the page does not zoom it in due to format of the page. I had to right click -> View image, in a separate tab in order to be able to zoom in enough to read the righthand side of it. edit: this is on the latest version of Firefox
