This guy is full of shit. The “roll out” depends on staging. Deep or shallow. Yes there can be a small difference in where you place the car in that box and yes that will affect your times slightly depending on how deep you are . If you deep stage to where you turn off the top bulb you could be less than a inch from starting the timer. That’s a red light waiting to happen. It’s why people trying to record a better number will bump into the bottom bulb. That’s called shallow staging. It will give a slower reaction time but better numbers down track. They are probably using the Wallace Racing Calculator to come up with the 0-60 mph numbers. If that car ran a 1.24 sixty ft, it’s hitting 60 mph in well under 2.0 seconds.
