Points System
8-6-4-3-2 points for the top 5 places and 1 point for the fastest lap.

Points for shared drivers are shared equally between the drivers, even if they drove more than one points-scoring car, unless one driver was deemed to have completed "insufficient distance".
The point is shared equally between drivers who set the same fastest lap time.
