I, too, appreciate the effort and agree with the comment that if I saw this before I throught about venturing into AG brewing, I would not have gone AG. I believe that this is simply a consequence of trying to accurately and visually describe any multi-step procedure.
As you look at the flowchart it does appear to be a complex process. However, that is the nature of accurately explaining a process in detail and then trying to represent it visually. I've taken training courses where we do exercises that ask you to describe the simplest process in detail as if you were describing it to someone who has never done it before (e.g., getting dressed, tying your shoes, making a pot of coffeee, etc). If you try to be accurate, detailed and go step by step, things appear to be complex even though they really are not. I remember the assembly instructions for old gas BBQ grills. They were super complex but if you followed the instructions and dedicated 2+ hours you got yourself a grill (now grills come in just a few pieces).
