The class will be qualified by positive reaction time (r/t) closest to “.000” based on a Pro .500 Tree. “.000” is considered perfect. Any negative r/t (-.001, -1.231, etc.) will be placed at the bottom of the qualifying sheet, the more negative the r/t is, the farther down the sheet the run will be placed. For cases in which identical reaction times are made, qualifying position will be based on a first-come first served: the first occurring r/t will be placed #1, the second occurrence of said r/t will be placed #2, and so on. Class will be random paired 1st round with higher qualifying positions receiving lane choice.

Deep staging is permitted, however not advocated. If you plan to deep stage, it is strongly recommended that you boldly display the words DEEP on all four windows, in plain view of the starter. It is always the driver’s responsibility to stage the vehicle prior to the tree being activated. In any event, the driver must be prepared to leave as soon as the final stage light is lit.
A competitor with the words DEEP displayed on the window is not necessarily obligated to deep stage.
