I agree that mine looks on to my--admittedly untrained--eyes but I had read discussion about a ~3mm deviation in various threads. My worry is that I threw a chain once soon after I first started riding fixed, since I was not maintaining the chain tension, when going down a sizable hill and I would not like to relive the experience.

The noise from a chainline discrepancy is not my concern as much as the safety/mechanics of it.
