Points are allocated based on number of starters.
Race 1 and 2 had 12 starters so the winner was allocated 12 x 4 = 48 points (doubled for R2). Points then decrease by 4 each position, ie 44,40,36,32,28.....down to last position who gains 4 points.
Since Forsythe missed R3 there were only 11 starters so the winner was allocated 44 points - then 40,36,32,28.......
Race 1 - The best 2 points scored by your team get added together and everyone in your team gets this total. So in your case Rocky, you scored 8 points, but Dammit scored 48 - thus both of you + Brake3 gain 56 points in the championship.
Race 2 is double points - which you won.
Race 3 you get the points you earn.....
