We re-ran the model as if standing at past dates, using only the data available then. Avg. error is the mean absolute gap between the median and what happened (percentage points); naive assumes no change from the last value. A well-calibrated 80% range contains about 80% of outcomes. Annual series have few test points, so treat these as rough. Methodology
