Conclusion: Just been playing for an hour. First twenty minutes I was tearing my hair out and then the penny dropped. You have to bring back your hand with wiimote the way you would a real dart and then thrust forward, releasing 'a'; it's all in the timing and composure - if you jerk too much you won't release the dart or it will go awry. Played a tournament, got to the final and lost by a whisker. Very tense really - like real darts. Shame you can't play on-line.
