If you had a shred of evidence, that would be nice.
Sadly he is not up with Truzzi's principle that "extraordinary claims require extraordinary proof". Or my extension of it: "some/any proof would be useful".
However, as there is none I will go with Hitchen's Razor; "what can be asserted without evidence can be dismissed without evidence".
With a touch of Hyman's Categorical Imperative; "Do not try to explain something until you are sure there is something to explain". Works well for Excel models.
