Sorry, but this ...
"[color="#ffffff"]Really bad, soft, out-of-acceptable range lenses do occur. They are fairly rare though and easy to detect."[/color]
... is bizarre.
If not it would the conclusion would be that all out test cameras are out-of-alignment.

That is in my opinion not his conclusions, but rather that all cameras are built within certain tolerances, as are lenses and if the deviation on both camera and lens go in the same direction, you will have more "misalignment" than the ideal specs. This is a very well known phenomenon within statistical process control.
The obvious conclusion is that one must have ones body aligned with each of the lenses in order to obtain the best results and it does not mean that either lens or body is "bad", just within tolerances.
