Sandy,
I'm pretty sure (someone correct me if im wrong) the point systems is worked out as following:
1st place recieves points equal to the number of people bowling in that particular round of the sports series, all the way down to last place recieving
1 point.
Say for example, 60 bowlers are bowling, whoever wins will receive 60 points, 2nd place, 59 points, and so on till last place receiving 1 points.
If there was 40 bowlers, 1st would get 40 points, 2nd place 39 points, and so on
