Points systems
Points are awarded to the top 10 (Pro-Am) or top 6 (Am, Trophy, Teams) classified finishers. If less than 6 participants start the race or if less than 75% of the original race distance is completed, half points are awarded. For the Endurance Race (Spa) points are multiplied by 2. At the end of the season, the 2 lowest race scores are dropped; if the points dropped are those obtained in the Endurance race, that will count as 2 races; however, the dropped races cannot be the result of disqualification or race bans.
