Well I saw some of the show last night. I did not see the incident referred to here. But I did notice they simply removed the amber lights and installed a green bulb in the middle of the tree. Rather than switching the tree to instant green, which some timing systems can do and apparently other cannot. By just replacing the bulb and setting the tree to a .400 tree its is entirely likely to go red, and by a fair amount. I heard David jones mention he did not turn o his delay box so the brake did not hold. Maybe the ONE bracket racer in their group is smart enough to understand in that arrangement of the tree it is quite easy to red light.
