That IS the basic definition of General Effect. The mechanical aspects of which you speak are the nuts and bolts of how and why these programs affect an audience... but the basic premise they all spell out is that which the original poster said... General Effect is measuring and qualifying the interaction of the audience and ensemble. As far as Madison's show... if you really break down that show, the only truly "toss the babies" moment was "Empire State Of Mind" at the end... it was an isolated moment... the best shows create moment after moment that build through each musical idea and throughout the entire show... Madison's show was all about the last moment, not the whole show.... so that's why, in my opinion, they didn't score as high, even with that HUGE moment... because that's all it was... one moment out of a 10 minute show.
