I bet it'll just be something the divisional points keeper will do. They'll only count one race per day towards your season points total, and will just pick whichever one gave the most points. Purely speculation though.

And yes, I'd be willing to bet that this is the direct affect of the Nelson quad, which had pretty much become a "must do" for anyone who was attempting to win a regional championship. A total points grab. Keep going down that road, and someone comes out with a three day "sextuple".
