Don't they score them over a number of races on a day?
I'm sure if you won the first race your car would then have a weight disadvantage (sand in boot or something like that
) for the second race.
Edit - "Under the three race format, the grid for the first event will be set by qualifying times. The starting order for race two will be determined by the results of race one – but with the top ten positions reversed. Race three's grid will be set by the finishing order of the second race."
It's nothing like F1.
