How it works. After you engage the clutch, the five red lights come on one second apart. They hold for a random 0.2 to 3 seconds, then go out together. Release on lights out. Releasing before then is a jump start, and anything under 0.100 s counts as a guess, since nobody reacts that fast.

About the numbers. Timing runs from the frame the lights go dark to your release. Your keyboard, mouse and screen add a little delay, so compare against your own times on the same device. Drivers on a real grid usually react in about 0.2 s.
