I often wonder if Nikon Service methodology is: "If it can be tuned with the camera's menu, then it is within factory specs. Doesn't matter if it needs a +20 or a -20.  If you can tune it, it's good enough."

I sent a brand new zoom lens in that wold need something on the order of -40 or so to tune (Sharply focused stuff behind the focus point was a city block away at times.).  Came back needing a -10, but at least it works.  Not at all linear over the various focal lengths either.

One tech said his own tolerance was + or - 5 points.  Who knows what the next service guy thinks is tolerable?  Maybe "If it is within the menu's AF tuning scale, next camera please." (i.e. "It's good nuff for me at +19.").
