"Heh, I wonder how helicopter owners would feel about their mechanic saying that?"

We have five mechanics here, and they take care of three turboprop airplanes and one helicopter.
One of our mechanics does pursue perfection, relentlessly.
I can't say that in the long run he does a better job than anyone else, but he doesn't seem as happy.
At some point it just gets silly and counter-productive.
So, I think the original perfection and good enough statement had something to do with mental health and not with the quality of the machine or the work.

Anyway, I have taken a harder look at my Pista.
The top of the tire does not center between the seat stays (off center to the right) but it does center between the chainstays.
I could have a misaligned frame from the factory, or maybe I need to move the hub to the left a little.
