. . . to judge someone's technique, I just know when their playing sounds impressive to me. They've got multiple scads of judges, though, all bathed in the same bath water, who will certainly pick the one they're supposed to pick, because they all know exactly what to listen for, and they'll all be listening for the same things, and the smart contestants will have been coached on what to play and how to play it. So all of that has already been taken care of. See what I mean?
