Qualifying Information, Ladder Type, & Tree
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 ladder, the more negative the r/t is, the farther down the ladder 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 paired according to qualifying positions, and then advance to eliminations.
