Where financial data
stops being comparable.
Test the assumptions behind a comparison. Inspect the definition, identify the missing evidence, and preserve an auditable research record. No synthetic observations. No invented source scores.

Dimension names are metadata, not measured statistical relationships.
Test another definition against this one.
Find the gap. Preserve the calculation.
Load two actual CSV series and compute period-aligned differences. Data stays in your browser. This is an arithmetic reconciliation engine, not an automated validation of statistical definitions or publisher vintages.
Period shift operates on Source B's sorted observation positions, not calendar arithmetic. Normalize only when index comparisons are meaningful. No automatic unit conversion or interpolation.
Upload both sources to begin.
| Period | Source A | Source B transformed | B − A |
|---|
A gap may arise from different definitions, vintages, units, coverage or data errors. This tool measures the gap; it cannot attribute its cause without verified source metadata. Preserve source identifiers, publication dates and licenses separately.
66 comparisons. No black-box score.
Every cell is derived deterministically from the published metadata. Select a cell to inspect the underlying evidence. Shared dimension labels are not proof of equivalent definitions.
Make your assumptions inspectable.
