Who is responsible and what review means
Shakti Prasad Ram is the publisher responsible for Go Calculator and its correction channel. The publisher identity is not a claim of medical, financial, legal or engineering certification.
Editorial review covers whether the displayed method matches the implementation, whether worked-example arithmetic can be reproduced, and whether units, assumptions and limitations are explained. Automated example and regression tests check software behaviour; passing them does not validate a model for every person or situation.
A page revision date records a content or implementation revision. A source review date records when a reference was checked; it is not the date the underlying rule took effect or evidence of independent expert approval. Effective dates are shown separately where relevant.
Formula before interface
Each calculator begins as a pure TypeScript function with explicit units, cross-field constraints and edge behaviour. Finance calculations use decimal arithmetic where binary floating-point rounding could materially change currency results. Investment projections distinguish effective annual return assumptions from nominal loan rates. Reference and edge tests are written before a page is treated as complete.
Source hierarchy
Government departments, statutes, regulators, universities, standards bodies and original research are preferred. A dated local ruleset records when a source was effective and when it was reviewed. A source link supports the named rule or context, not every assumption on the page.
Some calculations are direct arithmetic rather than externally prescribed formulas. Other tools deliberately use planning assumptions: for example, TDEE activity multipliers and the water tool’s fluid allowances are explicitly labelled assumptions. Background health guidance must not be mistaken for validation of those coefficients.
- Show effective and review dates near changing rules.
- Generate university variants only for genuinely different documented formulas.
- Keep fuel price and toll values manual.
- Treat currency reference data as dated and user-overridable, never live.
- Use regulator, standards-body and original-research references where a primary source exists.
Rounding and examples
Finance projections generally retain high precision until display; any model-specific timing or rounding is described on its page. For example, the health tools round the resting-energy estimate before multiplying by an activity factor. Whole material packs, bricks, tiles and break-even units round upward where partial units are not purchaseable.
Worked examples state their own illustrative inputs, substitutions and results. They are fixed teaching examples, not descriptions of the values currently entered above them. Reference tests use independently specified expected answers; the examples make no performance, eligibility or health-outcome claim.
Corrections
A correction should include the formula or source that changed, affected routes, effective date, tests added and review date. Material corrections should be logged before deployment rather than silently changing a result.
