Small Hours publishes practical browser tools and explanatory articles. Our standard is that a reader should understand what went into a result, what it can support, and what still needs checking. A calculator is a model of your inputs, not an independent statement about your business or a promise about the future.

Sources belong to the people who define the rule

Platform requirements are checked against the platform’s documentation. File formats and email authentication are referenced to specifications or official documentation where available. Competitor tools can help identify useful workflows, but their interface is not evidence that a formula or a policy applies everywhere. Each tool page links to the relevant references.

Examples should be reproducible

Tool pages include inputs, a result and an interpretation. The “Try an example” button runs supplied values through the actual implementation. Calculation tests cover normal results and relevant boundaries, such as a zero denominator, a negative contribution or a missing record. Browser checks cover behavior that cannot be established with a pure calculation test, including XML parsing, file downloads and image encoding.

Assumptions should be visible

Money amounts stay in the currency you enter. Period-based metrics need matching periods. Fee models use configurable rates because payment products, countries and contracts differ. We do not silently substitute a benchmark for your own retention, costs or conversion assumptions. A tool that inspects an export describes the supplied data; it does not claim to have crawled your website or connected to a private analytics account.

Content and code can use AI assistance

AI can assist with research, drafting and implementation. That does not make a generated explanation an expert certification. We check examples against implementations, prefer primary references and describe unsupported cases. We do not invent named reviewers, qualifications, customer results or traffic statistics. You should compare a result with the underlying report or source before relying on it for an important decision.

Changes and corrections

Platform fees, policies and browser behavior can change. Source links give you a way to inspect the current rule. If an example differs from a result, check the selected mode, units, time period and any custom fee inputs first. The corrections form prepares a report with tool name, sanitized inputs, expected result and observed result. Our publisher profile explains who is credited and how examples are prepared. Do not include private customer records, credentials or financial files in a public report.

Useful content comes before length

We add instructions, worked examples and FAQs when they help complete the task. We do not treat a word count or a number of questions as a ranking formula. Google’s guidance favors helpful, reliable content and explicitly says it has no preferred word count. Rankings and indexing remain outside the control of these calculators.
