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: Under some circumstances, the average among the 12 cities in our national prediction model may move in the opposite direction from what we predicted, and yet we still consider that a successful prediction. These circumstances include: 1) "Steady" pressure, where prices may move in either direction within a predicted range; 2) "Mixed" pressure, where some of our 12 cities are trending one way and some the other, and the actual net result may be different from what the average trend suggested. In either of these cases, we publish the predicted range for the next day's average prices, and we call it a successful prediction if: a) the actual change in average price was in the direction indicated by average pressure, regardless of the amount of the change; or b) the next day's actual average price was within the predicted range.

Key

• 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.
