I watched some of this!
Damn Australian broadcast only showed one heat, the one with an Aussie in it. (Well...at least that's all I saw. I only switched to the channel by coincidence just before that heat happened. And then during the subsequent and final heat, they didn't show anything...just showed an interview with the Aussie who came like 4th in his heat...which was good enough that he might make the semis if the 4th place in the final heat doesn't beat his time, IIRC.)
But as a sport it looked really interesting. I wish they had shown more of it, and I'll be keeping my eyes out for it in the future. It was very exciting and dynamic in a way that, for me, most Winter Olympic sports kinda aren't.
