If it helped as much as 40% would be a big help . I started racing with a flagman if the flagman did`nt like you you had a problem . So many fights back then cause of getting flaged that something had to be done . There was a fight at almost ever race then they cane out with the tree . But in those days there was no rec times or 60 ft times you was eiher green or red . At that track there was a flagman at the end of the finish line he would raise the flag for the winner .
