It was entertaining, that's for sure. I'm not sure the new scoring rules make a huge difference. As Laura Trott was quoted in The Guardian, she went into the points race knowing exactly what to do, stick to the wheel of the woman in 2nd place going into the race (a Dutch rider, I think), and that is exactly what she did, bar one sprint when the other rider got the 5 points followed by Trott winning 5 points at the next sprint, thus ensuring her win.
TBH, I think the omnium is a sop that the Olympics used as an excuse to get rid of a lot of other events. My favourite is the Madison. The TV pictures never quite captures the atmosphere of being there.
