Every single top score on my personal machines was achieved while under the influence. Has nothing to do with duration of play or determination. Somehow, in some way, I play significantly better with a few beers in me, and I'm talking like wizard mode better, not just a slight edge. Maybe it is due to some sort of competitive edge from being around friends hanging out while drinking, or maybe I'm a bit more relaxed, but I'm in no way a competitive person, and I could care less about beating someone in a scoring competition. Either way, for me, beer + pinball = a high score.
I wanna see a show of hands here, I can't be the only one. And they told me reaction times were slowed by alcohol in health class!
