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.
I looked at the 2011 rules and it was close to that. Curved track. 25 pts for each second. 10 pts for each cm.
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.
