I hadn't thought about this approach before, but I think it would be a helpful way to strategize. I agree with you someone about tutorials and the quest for wizard modes. I tend to benefit from them to some degree, but I'm not yet a skilled enough player to execute many of the strategies discussed. I don't have games of my own, so my opportunities to practice are limited by money and time (fortunately, being that I live in Portland, not a shortage of places or games to play) and the information from tutorials can overwhelm me. On the other hand, when I watch people at weeklies play I tend to pick up tips and see some things I might want to avoid, so I see how watching qualifying rounds could help in a similar way. So thanks, @mizary for this idea! It might really help.
Likewise, as you said, thanks to all those who are recording and sharing pinball for us to learn from (or be entertained by)!
