I looked at the 2011 rules and it was close to that. Curved track. 25 pts for each second. 10 pts for each cm.TBH it would be great if there was like a x10 time multiplier and a x2 distance or something like that. Time wasn't a big issue this year, but there were teams which beat others because of the time score, even though the distance score was worse.
Anyway speed meant a lot more last time they had a curved track. But batteries were limited as well.
Personally, I like the way they did it this year.
