Due to the constant changing of the rulebook, we have added a fasttrack page to update the major changes that will affect you.

Big change in how points are scored!
1st place gets 1000 points
1st place time / 2nd place time x 1000 = 2nd place points
1st place time / 3rd place time x 1000 = 3rd place points and so on

You also drop your 3 lowest point races! It should help keep big classes closer in terms of points by the end of the year.
