A redraw is a random draw among the top heat race finishers for the front rows of the feature, so a driver who won a heat might pull the pole or might pull sixth.
A redraw is chance, and it is public. World of Outlaws late model racing sends the top six to eight drivers to the front stretch before the Last Chance Showdown to redraw for starting positions. IMCA sizes its opening-night redraw to the program: five with one heat, 10 with two or five heats, 12 with three, four or six. Miss the redraw and you line up by heat finish behind the drawn cars. This is where redraw and invert get confused. A redraw is random — you can win your heat and pull sixth. An invert is a formula the rulebook already wrote down, so you can do the math before you unload.
Because a redraw is luck, winning your heat only buys you a ticket into the draw rather than a front row start, so bank track position where you can actually control it.
