Open calculator methods and reference data

The public data here describes calculator methods and published race-entry references. It does not contain athlete records or a claimed study of 500 coaching clients. Use the formula notes to reproduce a calculation, check the source and edition, and understand the assumptions. Original coaching outcome datasets will be published only after consent and anonymization review.

Which data is available now?

The 25-tool inventory, formula descriptions, input assumptions and source links are available in the calculator methodology and machine-readable public reference file. Boston and New York entry references are labeled by edition.

Where is the 500-athlete dataset?

There is no published research dataset behind that biography count. The owner-confirmed number describes athletes coached. It must not be treated as a statistical sample or a performance study.

How should I cite a calculator?

Name the tool, input values, method and source edition. State whether the output is exact arithmetic, a physiological model or a heuristic conditions scenario.

Where does this guidance come from?

Primary source and methodology. Use the calculator’s method notes for assumptions. Coaching decisions still require your context.
