Write to [email protected]. Corrections to the physical model or the reference ranges are the most valuable thing to send, because a fault in the arithmetic affects every result the instrument has ever produced, not one page. A single bad coefficient is worth more attention than a dozen typographical slips.
What is worth reporting
A coefficient that is wrong, a duration curve that does not match published performance data, a platform behaviour that has changed since a page was written, or an instrument producing an absurd result from reasonable inputs. All four get fixed; none of them gets argued about. If the model is wrong, the useful response is a corrected model.
Disputes about a specific athlete or a specific segment record are not something this site can adjudicate. The instruments report what figures imply, and the interpretation of any individual result belongs with the people who have access to evidence that arithmetic cannot supply. A power file, a photograph or a training partner will settle such a question; this site cannot.
What happens to a correction
The page is changed. Where a published figure moves, the text moves with it instead of carrying a note about a previous version. A model change is applied across every instrument that shares the affected code, because the plausibility check and the calculators use the same duration curve. Fixing it in one place therefore corrects every reading the site produces.
