Different categories within class? How scored?
Could someone explain how scoring works between different categories in the same class?
The news broadcasts seem to imply that all cars compete against each other - the same for trucks. Yet, in cars class, there is the Improved and Production category, as well as Open. (By the way, where does the Hummer Buggy fit?)
Is there one winner in each class, or are there separate winners in each subcategory? What category are the main competitors, the Minis, Toyotas and the now-departed Tuaregs?
