What is really needed (in cases like those being discussed here) is a fuller check going to the extremes of acceptability, and perhaps then they'd be able to diagnose and fix marginal situations. (It's entirely possible that away from Canon's R&D the test gear can't do any better, and we suffer as a result.) That's certainly what we used to do when servicing electronics gear - our test equipment was programmed to check performance not only at the mean position, but also to explore the performance out to the 3 sigma position. But then our taxes were footing the bill...
