    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.
