So solo dance is something for maniacs, not even average skating fans can't understand, let alone ordinary people.
But the "average fan" can tell if you stood up or not. I don't suppose there'll be a lot of people falling on twizzles?The "average fan" can't tell if a jump was done well or not (proper edge, full rotation, etc),
Solo dance does present some challenges in judging (as well as a lot of sport/not sport debates). Rather than comparing it to singles, better to compare it to ice dance. My conclusion: it's even harder to understand and judge, because in ice dance you have holds, lifts, and side-by-side twizzles.
