So - I read through this once - and at various moments put in comments as I was reading and making sense of things. I scribbled some notes on a separate paper so that I would focus on reading it as a whole, first. I also had the annotations from others visible and sometimes would glance at those. Now, I'm coming back to those comments and putting them in. I say this because it seems important to share my process - experience the paper, experience other's comments, and write down ideas i hope add value in some way.
I agree with Linda in that there is an aesthetic quality to the piece - the paragraphs each have a key point and they flow almost like a poem. The nautilus shell metaphor also seems to hold particular meaning (spiral metaphor that has other larger qualities such as the golden ratio). I am wondering if this can be leveraged more - and seeing Linda's first comment changed the way I read this - which makes me think this might be valuable to other readers. What did it do, you ask? I took on a different mindset of watching the "flow of ideas" (unfolding), and that if one idea was a bit difficult to follow - to just stick with it like I would a poem because I know I'll hit something later that will give me the missing "aha". This also helped disrupt me from the way I might read a manuscript as a reviewer. So what else did Linda and Liz do for me - they helped me take a reader stance of "thought experiment", "reflective moment based on 10+ years of experience", a desire to influence change. They have known you for a long time - and they both commented on the value of being able to watch your journey and see this culmination. The typical reader won't have that to draw upon - so, is there something you can do that can set up the experience of reading this in a way that seems to be something you would want? This can be visual cues - pattern cues (starting each paragraph with an "in my model" repeater) - personal cues ("the 20 year journey of my model")...small, little things.
