My 4th on Primal Road in Dragon Kart isn't the best, but I'm not sure how they're shaving 3.8sec off of a pretty clear and cut line... My best ideas are: due to the fact that you aren't boosting 100% of the time, it might be better to coast off of your boosts a bit more on straights, and perhaps ride the curb tighter... I've got to take 2nd before I can really complain, but I don't trust SEGA kart racer leaderboards anymore. :c
