I am a computer hacker that has dipped into physiology to perform at athletic extremes to good success. I always rely on data and evidence, and refuse to take advice on physiology from anyone (including doctors), because very few stick to evidence-based strategies (and doctors seem uninterested in sports physiology). Physiology is many orders of magnitude more complicated than any computer system I've worked on. It is easy to create abstractions that try to explain some of the data, but you must always be ready to have them proven wrong when you look at the next layer down. Evidence must rule.
