How this engine reports
- Measured evidence — labelled on every number, never dressed up as more certain than it is.
- Works with pasted answers — no API keys required.
- Reads your archived measurement runs.
- Every rate ships with its sample size and a 95% confidence interval; results below n=3 are flagged low-confidence.
