Agile is estimated from the actual half-hourly prices of the last 30 days, using a typical-home daily shape (more in the 4–7pm peak), with your “shift” share moved into each day’s 4 cheapest hours. Past prices don’t guarantee future prices, and Agile prices change with the wholesale market and season.
