when you come to a stop, the telemetry gauge resets itself. as you accelerate, whether hard or normally, the telemetry measures to a quarter mile, and when it gets to that measure, it tells you how long that it took you to get from a stand to a quarter mile, then how fast you were going at that measure. it also measures from a stop to 60mph and tells you how long it takes. the gear line items tell you how fast you are going from a stop at each shift.
