Why would the points reset? It's a series prize, hence all 4 events taken into consideration. I love the series but I have never heard of this happening in any other series w/o being announced before the first event.
That's how we did it last year and it was put out at the beginning of the year. We do this because I like the concept of 2 series prizes. Race to Chicago and race to World Cup. It allows teams that had a rough first half to put it together for the 2nd
