A useful tracker should make the reported measure visible before the interpretation. For each row, capture the legal or policy basis, the reported measure, the calculation basis, the implementation status, the next evidence update, and the person or function accountable for keeping the row current.
Do not collapse planned policies, implemented measures, and measured savings into one percentage. Keep them as separate status types so a visitor can see whether a row is backed by measured energy data, a national plan commitment, a programme record, or a transposition note.
If an internal dashboard still uses a rate, publish the numerator, denominator, cut-off date, exclusions, and evidence rule beside it. For example, an audit-completion rate should count only the defined obligated population and should not mix completed audits, EMS-route enterprises, exemptions, and unresolved threshold assessments in one numerator.
