Thank you. I was thinking of feedback from people experienced in some complexities of backpacking / camping. In the past, I helped people traveling to Tibet and close to El Chalten [1] with GPS, batteries, solar cells, and weather schedule and redundancy, since if you don't organize yourself precisely like a "military campaign" something could fail that could be prevented with an engineering process.
