David Miller writes and maintains the Blogyz Calc tools — the sports, fitness and biology calculators on this site. Each calculator is built around the standard published formula for its topic (the source study, rulebook or reference dataset is named on the page), tested against worked examples by hand, and reviewed periodically for accuracy. The tools are provided as general reference and planning aids: they are not a substitute for professional medical, veterinary, coaching or laboratory advice, and every page carries a note on the limits of its formula. Corrections and questions are welcome through the site's contact page.
