How the predictor learns

Every forecast is stored. When Wise publishes the real rate for that day, the miss (delta) is written to a learning table. Each run, the last 60 days of misses set how much each model is trusted at each forecast horizon. They also set a bias correction, which is switched on only when it has actually reduced errors.
