My "brand" of Engineering is just Engineering. I am really glad you are happy to have no association with it, because it would be a slur on my work if you did, given your twisted logic. My analyses would have to be wrong to fit with your logic.

See I don't need to answer your questions, because they don't matter in the bigger system. It is the bigger system view that counts, the energy auditing has to all stack up, from end to end, and it does, I've shown all the maths, that you keep demanding, only you will probably never know, because you will have to cover all the 400 odd stories I've written on the subject, with formal Systems Models always underpinning everything, to understand the bigger picture, you would need to know all system modeling languages used to express that model.

This is reality.

And you are wrong about Medium being just a social media platform. Here, the majority of folk are thinkers, usually with formal qualifications, who can spot shysters like you from ten paces. You seem to be lacking the intelligence to be able to see that. You are not dealing here with average Joe public, who might not think at all.

All the best "Ian", if that is even your name, I hope you can at least be trusted to keep your word, to have no association with my work.
