(https://graham64.wordpress.com/2014/11/19/brisca-roof-colours/)
Drivers pick up grading points in every race in which they compete in. At the end of each monthly grading period, a drivers grading points are used to check whether they are in the right grade. It is possible for drivers to be both demoted as well as promoted, up and down the grades.
- “White Tops": Low ranked/new
- "Yellow Tops"
- “Blue Tops"
- “Red Tops": Highest ranked/fastest
- "Silver Top": National points champion
Each grade forms a block of cars lined up two abreast and bumper to bumper, with a two-car-length gap between each Grade. The White Tops start at the very front, followed by Yellow, then Blue, and the Reds at the very back.
A driver who has been newly promoted to a higher Grade will be lined up towards the front of the new grade, and a driver who has been recently demoted down a grade will be lined up at the back of his grading.
The amount of drivers at the start will determine the amount of point to be earned at each race. First finisher will gain #drivers+1 points, last finisher will not gain any points. For a race with 6 drivers, the points will be given as follows:
- 7 points (6+1)
- 5 points
- 4 points
- 3 points
- 2 points
- 0 points
Attendance points will also be given to benefit those that are willing to travel. This will be 1 point per meeting (not per race).
