Thanks Greg. Your real, and thats what we need around here. As for the accuracy, all i can tell you right now is that he reset his average mileage, then drove to my house. He got 35.6mpgs. After the groove before leaving, he reset it again. When he got home he got 40.8mpgs. He also reported great increases for his current mileage for 60mph flat roads. He wants to do a follow-up video in 500 miles. I'll keep everyone posted.
