The third light beam is only 12 or so inches in front of the staged beam. So, you have the pre-stage beam, then a gap of a few inches, then the staged beam, then another gap of a few inches (larger gap than the first), then the third beam.
You have to have both the pre-stage and stage lights illuminated prior to the tree starting its countdown. You then launch and if you hit that third beam before the green is lit you get a red light. --- Basically the third beam does the same function you are used to having the uncovered stage beam do.
does that make sense?

Yes, it does, but I don't quite understand why its not like a regular drag strip.

The rules state that a perfect launch is a 0.500 reaction time, just like a typical strip timer...so does that mean that you actually have to start a good bit earlier than you would at a dragstrip in order to get close to a 0.500 RT? (i.e. you have to trip that third beam in order to trigger the timer)
I suppose since they are triggering on a third beam interruption (i.e. just as the front of the tire blocks the beam) that it may be really close to the staged beam being uncovered -- does that make sense? I wonder why they do this. Do you know what the rollout distance is and if it is comparable to a typical strip?
Thanks,
