Then again, on yet another hand, another aspect of 'effectiveness' is dealing with the unexpected. Ukes who attack in ways you didn't expect, who counterattack in ways that weren't planned ahead of time. Which is valuable in training but I don't see so often in demos (I don't often see it in either the demos I like or in the ones I don't like).
Maybe it's the nature of demos, that they're something that's planned, and it's pretty hard to plan a surprise? Or it's just not what people demoing see as the purpose of a demo?
