Serious question: what does it mean that perfect accuracy is a bad thing? I'm not a pianist and I'm not a professional, but I'm an amateur oboist (20 years in student/amateur orchestras). I think of technical accuracy as necessary but not sufficient for playing music. When I really have a piece down technically I can focus 100% on musicality, but I want the technical parts down solid.
Of course as I'm practicing, I am deliberate at working on both the technique and playing expressively. If I'm not deliberate about it, it's too easy to just focus on nailing the technique - it's a lot easier than the musicality.
