Thanks for posting these. I’ve built my own leaders for years using some “general” principles but nothing as specific as you have presented. Fortunately, I arrived pretty close to your formulas completely by accident.
When I dove into this subject I became amazed by the complexities of the leaders. Then I understood the physics and it became clear. Mass moves mass, simple as that. I have always found, that by writing "stuff" in such a way that anybody can understand it, that only then do I understand it. I hope I have done that in this case. If explanations do become complicated then most often they are not right.
