The rules are posted under the 9 second tab on the top of the page. Ties will be broken by whomever ran the time first wins that position ( I guess this is where "the luck of the draw" comes into play). March's event will count for actual points toward the 9 second championship, and in addition 5 bonus points will be awarded to each class your truck would be legal for in the Lee County Mud Motorsports Complex Points championship.
