What does this number establish?

Use the underlying definition.

Explanations should link official explanations of inflation, national accounts and financial statements. The relevant statistical institution and reporting framework matter to interpreting a figure.

Label illustrative arithmetic.

The price notebook starts with a fictional index of 100. The business example uses invented amounts and explicit simplified assumptions. Neither is an observed series, company account or forecast.

Preserve source boundaries.

The archive retains supplied references and notes. General resources are not upgraded to claim-level corroboration, and allegations remain distinct from official findings or attributed responses.

Respect date precision.

Original supplied dates remain with the earlier record. The rebuild does not reset historical publication dates or treat a redesign as an article revision.

Build future research on a stated method.

New original research should identify its question, source selection, collection period, method, calculations and limits. An explanation of existing material should not be presented as original data collection.
