not getting an expensive gtech, but I could setup a video camera to focus on the speedo, and hit the go pedal and upload it for you guys... set the timer, or when it's uploaded to Utube, use it's timer to verify my time.
that would eliminate the human side of errors, but would not be truly accurate.
