Corrections are the most useful thing you can send
If a calculation looks wrong, a citation does not check out, or a claim on this site does not hold up, please say so. Include the page and what you expected instead. Corrections get made and recorded in the changelog rather than quietly edited away.
Field data is welcome too. If you have measured energy expenditure while rucking with a metabolic cart or a well-calibrated device, and you are willing to share the numbers, that is exactly the kind of evidence needed to improve the load-ratio correction at slow speeds — a known weakness set out on the methodology page.
What we cannot help with
