A maker should have a great idea how the cue will play after the butt has been assembled and in near final size.
They shouldn't be making cues if they're not coming out with a solid hit -- however, to imply that there's something special about a cue in production because they "can just tell" is, to me, just hype and an attempt to give the guy who's been waiting way past his promised delivery date a warm wet feeling and not much else.
