The ADI Backtest After the Family Rebuild

The old backtest page read the retired ADI file directly. That was useful during the measurement rebuild, but it no longer describes the public index. This replacement keeps the backtest question and routes readers to the family method.

The family-v1 ADI averages five equal-weighted domains. Each input is ranked against its own quarterly history, and each domain is the mean of the inputs present for that quarter. The published composite is a mean of input percentiles, and quarter-rank context comes from the separate rank-in-history field.

The ADI reference page publishes the maintained national reading with its required band gloss. This snapshot does not embed that changing value.

For the full historical series, use /api/adi.json. For the methodology contract, use ADI methodology and the machine-readable methodology emitted by the family engine.
