GasPredictor.com's Track Record

Since we began publishing our national predictions daily in November, 2008, we have been correct over 99% of the time.

* Note: On July 27, 2010, prices moved in the opposite direction of what we predicted, but there was mixed pressure among the 12 cities in our national forecasting model. Under those conditions, we calculate both a general direction and an acceptable range of average price for the next day. This is because, although the numerical average pressure among the 12 cities points one way, the actual change in average price might be in the opposite direction. In this case, this is exactly what happened. We predicted generally downward or upward pressure, but enough individual cities had pressure in the opposite direction and, as it turned out, actual movement in that direction, so that the average price moved in the opposite direction of the average pressure. Since the average price remained within our predicted range, we call this a successful prediction. In such cases, we publish the predicted average price range ahead of time, and we state ahead of time that we will consider the prediction successful if the final situation works out this way. We're not trying to cheat! This is the change in our prediction algorithm that we introduced after March 26, 2010 when each of our local predictions was correct, but the average price moved opposite the direction indicated by average pressure.

Key

• Date of Prediction - The date we issued this prediction, pertaining to the next business day.
• Buy Today Recommended? - Did we recommend buying gas that day ("yes"), or waiting to buy gas the next day ("no.")
• Next-Day Actual Price - Which direction did retail gasoline prices move the day after our prediction?
• Correct? - Was our recommendation correct? Would you have realized a savings, or at least not realized a loss, by following our recommendation?

Our prediction algorithm is designed to predict the change in retail price of regular unleaded gas at the second cheapest gas stations. Each day, based on that prediction, we recommend whether to buy gas today, or whether you would come out ahead by waiting until tomorrow. We check our prediction against the most recent available prices at the second cheapest gas stations in our test areas. If you would have saved money, or not lost money, by following our recommendation, we call that a successful prediction.
