I think what he means by "dialled in" isn't the same as the term "phoned in". He means having the show running slick.
But I don't agree with his assessment of why fans want different setlists every night. It's not because people go to multiple shows, necessarily. He's right to say those are the minority. For everyone else, they want different sets because they like not knowing what they're going to get. They like to be surprised by a progressive band.
