Original task-focused explanations
Each page explains its actual calculation task in plain language. Keywords guide topic ownership; they are not inserted as unnatural phrases or treated as evidence of financial facts. Research volumes are not represented as traffic forecasts or ranking guarantees.
Check examples and preserve assumptions
Worked examples are tied to explicit amounts, units and timing. The calculation engine has automated tests for published fixtures and important boundary cases. A passing mathematical check supports the stated arithmetic only; it does not verify future returns or substitute for a professional review.
Use attributable factual sources
Historical price data identify the statistical series, observation coverage and source. Spreadsheet and device instructions reference primary documentation. No expert endorsement, biography, testimonial or invented institution is used to create an appearance of authority.
Dates and corrections
Publication dates record the initial creation of the content; they are not dynamically relabeled as updated today. Corrections should identify the page, input values, expected behavior and source or arithmetic supporting the correction. The contact page currently lets you prepare and download a draft; delivery remains unconfigured.
