So I did a 1/4 mile run today, way out on the highway using the track apps, excelerate to start. I live at around 2200 ft and it was 21 degree's celcius. I spun a little in first and bounced off the rev limeter in 4th, granny shifted and the recorded time was 13.0 at 114mph. How acurate do you think this is? I've never been on an actual track before. What is your best time using this feature?
