I like to look at the g-meter and set my zero time to the point where it begins to rise. My reason for this is that until that begins to climb, the car can't be moving. I'm interested to hear others' thoughts!

Don,
Good point. I agree the first G meter movement may be the way to go.
Let's see what others have to say.
