good question Fazz .. we struggled a bit to find the right way to do this and this is what we did.
after the race the total race time of everyone in class 1 and class 2 are then compiled/ranked into 1 list and points are then awarded for positions 1st to 15th in this list ..
that means the 1st position winner in class 2 can now be ranked 9th in the overall list and he will only get 9 points instead of the full 20 points ..
this will encourage class-2 karters to improve and move to class-1 because of the chance of earning more points …
