SECTION 4 - POINT SYSTEM

4.1 POINT SYSTEM
Points will be awarded at all WISSOTA sanctioned events on the following basis:
4.1.1 General Points go to the driver. The driver will receive the best point finish
between the heat race or the consolation race event before entering the feature (one event only).
4.1.2 Eligibility for Points If a race car pulls out onto the race track, under its own power, with the intent to race, then the driver will receive the points for the finish in that race.
4.1.3 Show Points All drivers in each class participating in the race events at a track will receive show points based upon the number of cars participating in that class, as follows:

4.1.3.1 1 to 9 cars participating, ten (10) show points.
4.1.3.2 10 to 15 cars participating, eleven (11) show points.
4.1.3.3 16 or more cars participating, twelve (12) show points.
                Participating means that a car must take a green flag at some time during the racing program, including hot laps.
    Summary
    1-9 cars = 10 show points per car
    10-15 cars = 11 show points per car
    16 or more cars = 12 show points per car

4.1.3.4 DNF (did not finish). Points awarded to DNF cars based on the order in which they were lined up at the start of the race (1st lap) or number of laps completed. Any car judged to be at fault for restart/accident will be scored behind any others who completed the same number of laps or were involved in the same incident.
