    How the figure is produced

    • Every report records its publication date, last-reviewed date, data period and methodology version.
    • Reports that rank or score include a downloadable table so the figures can be checked independently.
    • Reports describing a past period are labelled historical rather than presented as a current comparison.

    • PowerGuardian public data register — research datasets
    • Each report lists its own primary sources on the report page.

    What this figure cannot tell you

    • A report describes the period it covers. Later market movement is not retrofitted into it.
    • Not every report has a downloadable table — only those built on a scoring or comparison dataset.
