Hi Tim
in essence, you get 30 points for recording the most laps on the night during the finals and also in qualifying. So if you win the B final with say 35 laps and the A finalists only score 34 laps then on the night you will score 30points for finishing the finals with the most laps. Effectivly what you have done is finished 1st in an A final but we had two finals on the night and in the previous final more laps were achieved by two other drivers hence you scored only 28points despite winning the final.
So maximum points gained during teh night is 60 (30+30). Best qualifying laps across the two heats and best final laps recorded across both finals if two are ran.
Hope that makes sense
