What is proof level?

A proof level rates how strongly a finding is proven: Counted (from observed activity) beats Compared (versus a peer benchmark) beats Estimated (from assumptions). It tells a CFO which numbers are hard facts and which are projections. Spendassay tags every finding with its tier and exposes the formula behind it.

Every figure Spendassay publishes about proof level carries a proof level saying how much guessing sits behind it, and opens to show the rows it was computed from. The full method is on the methodology page.
