Editorial Policy

Last updated: 2026-05-17.

This Editorial Policy explains how FitMetricLab creates, reviews, and updates content, tool labels, formula notes, and methodology citations.

Effective Date: 2026-05-17. Publisher: Brightscale Labs Limited.

1. Accuracy and mathematical integrity

Every calculator on FitMetricLab implements a published formula. We use defined calculation rules and repeatable QA checks before publishing tool content or updates:

• Formula standards: we use the original published formula: Mifflin-St Jeor, Katch-McArdle, Jackson-Pollock, Siri, Karvonen, Daniels VDOT, Coggan FTP zones, IPF DOTS, Wilks, Brzycki, Atwater factors, and their peers. Not in-house variants. Where multiple variants of a formula exist, the tool page names which variant is used.
• Sources: each tool page links to the primary published source. Where the source is a peer-reviewed paper, the PubMed or DOI link is provided. Where it is a federation reference (for example IPF or ACSM), the official publication is linked.
• Edge-case testing: we test boundary inputs (very low and very high) and unusual scenarios (extreme body composition, masters-age athletes, edge of formula validity) to verify stability and consistent outputs.
• Test values and expected outputs: every tool ships with a test input set and an expected output. The build pipeline runs the math engine against the test inputs on every change. If the result drifts, the change is blocked from release.
• Human review: tool logic, labels, methodology notes, and FAQ copy are reviewed by a human editor before release.

2. Transparency and AI disclosure

We disclose where automation is used and maintain editorial review:

• We may use AI-assisted drafting or structuring for selected content (for example formula descriptions, FAQ phrasing, methodology summaries).
• Mathematical formulas, constants, and references are not generated by AI. They are taken from the named primary source and verified by a human against that source.
• Published content is reviewed by a human editor before release.
• AI-assisted content is checked against the named primary source for factual claims and run through our advisory-language scanner before publishing.

3. Update and review frequency

We use a scheduled review cycle plus ad-hoc updates when methodology, published guidelines, or platform behaviour changes:

• High-use tools are reviewed at least every 90 days.
• Other tools and reference content are reviewed at least annually.
• Critical fixes (formula errors, mislabelled outputs, broken sources) are published as soon as practical after validation.
• Each tool page surfaces its Last updated date so readers can see when it was last touched.

4. Independence and objectivity

Our editorial process is independent of commercial influence on calculation outputs:

• Advertising (Google AdSense) does not change tool formulas or result logic.
• Affiliate links, where present, are clearly marked and do not influence the methodology of any tool.
• Product and content decisions are based on usefulness, clarity, and technical reliability, not on advertiser preference.

5. Compliance and tone

FitMetricLab does not provide medical, nutritional, or training advice. All content is written in an educational tone: describing what a metric is and how a formula works, not prescribing what an individual ought to do. Our build pipeline runs an advisory-language scanner across every tool page before deploy. Prescriptive directives, second-person commands, guarantees of outcome, and similar advisory phrasing are blocked at commit time.

6. Corrections process

If we identify a material error in a formula, output explanation, or methodology note, we correct it and update the relevant page as soon as practical. Where the correction materially changes a previously-shown result, we add a brief note describing the change and the date. Users who spot errors can report them via contact@brightscalelabs.com or our contact page.

7. Scope and limitations

FitMetricLab provides educational tools and explanatory content. It does not provide medical, dietetic, physiotherapy, or coaching services. See our Medical & Fitness Disclaimer for the full scope of what the site does and does not do.

8. Privacy references
