Corrections Policy

OverCalculator aims to correct calculator and reference errors clearly and in proportion to their effect. This policy covers formulas, implementation, units, defaults, rounding, assumptions, sources, explanations, and labels.

1. Send a report

Email [email protected] with the page URL, inputs and units used, result shown, expected result, your calculation, and any supporting primary or authoritative source. Describe possible consequences if the issue affects health, money, safety, or a legal or regulatory obligation. Avoid personal or confidential information. More guidance is on the Contact page.

2. Assessment

The report is assessed against the stated method, cited source, live implementation, units, validation, rounding, and explanatory text. Relevant boundary cases or worked examples may be repeated. Priority depends on likely impact, not on who submitted the report. A different result may reflect a valid alternative method, jurisdiction, date, or assumption rather than an error.

3. Correction or update

If a problem is confirmed, OverCalculator may correct the formula or code, replace or qualify a source, clarify assumptions or limitations, fix a label or example, or temporarily restrict a tool while the issue is resolved. If no error is found but the page can reasonably cause confusion, the explanation may still be improved.

4. Dates and material corrections

A material correction changes the output, method, important assumption, safety or decision context, or meaning a reasonable user could take from the page. A confirmed material correction changes the page's Updated date. When earlier use could remain misleading, the page may also carry a visible correction note describing the affected behavior and the change. Minor spelling, formatting, and presentation fixes do not by themselves change the date.

A date records the material page change; it does not certify that every source or externally maintained value was rechecked on that date.

5. Reconsideration and escalation

If you disagree with an assessment, reply to the same email thread with the specific point you believe remains unresolved and any additional source or reproducible example. Ask for reconsideration in the subject or message. The issue can then be reassessed at the organizational level using the available evidence. OverCalculator does not name individual reviewers or promise an outcome or response time.

Scope

This process improves the published utility but cannot make a general calculator suitable for every individual case. For consequential decisions, verify the current result with the relevant authority, institution, original source, or qualified professional.
