Yeah, my last two times were done with D.K.JR. My best lap time with him is 21" something, but that was the first lap, and I always need to let off the gas slightly in the first corner if I get a boost start, since the start position isn't far enough to the right to make that turn normally. If I did a lap that good after the first lap, it should be 20" something, but at the moment I'm running at about 22" for a normal good lap and 23" something for a bad lap. I think there may be something in trying to maintain the boost speed from the start - but I need to experiment more with that. Yeah, drifting is just r-trigger while accelerating. Drift round 180 degrees and don't hit anything on the turn or the exit and you should get it. There's a borderine exploit which according to some reports involves drifting, jumping, hitting walls, all sorts, which I've not got my head around yet - but the normal drift boost just needs R and B.
