I can’t understand how the points are allocated!

For every race (Moto) you complete, you are awarded points. The higher the position, the more points you get. If you get as far as the final, then you are awarded more points. The table below demonstrates:

Position Moto B Final A Final
1 4 15.0 42.0
2 3.5 12.0 37.0
3 3 10.0 33.0
4 2 8.0 29.0
5 2 6.0 26.0
6 1 5.0 24.0
7 1 4.0 22.0
8 o.5 3.0 20.0
