The race where Lawless ran a 12.004 and the other guy ran a 12.02 but won with a holeshot what does that mean? Yeah I know, but there are no stupid question, right??
It means that even though Lawless ran a quicker time the other guy actually crossed the finish line first.
Your reaction time starts when the green bulb is lit but your elapsed time doesn't start until the car actually moves and breaks the beam and the staging lights go out.
Theoretically you could sit at the line and not move for 30 seconds but still run a 12.004 or whatever your car is capable of running.
