No. Not until Apple, or someone else, finds a flaw in their test method(s).
But you can only assume that nobody actually thought about it. Also. Their numbers are real, but they might be obtained in the wrong way. Yet they do depict a problem. Whatever that problem may be, to be determined at a later time, and that is why we need independent reviews to verify, and either confirm the 'problem' or debunk it. No speculations, assumptions and personal opinions. Facts and facts only. Nothing else counts.
Note: If it was an obvious flaw in CR's testing methods, then Phil Schiller would have been keen to push out a new tweet, and before you can blink with your eyes, yet that did not happen, so it may actually be a complex problem. More so than what most people here seem to think that it is.
