the most important takeaway is that just because a well respected photographer says something about exposure, development, contrast, chemicals etc doesn't mean we should simply accept it as fact, especially in cases where no evidence, or a proper description of the experiment is given. And the description of the experimental method is very important. Even when presented with data (a characteristic curve for example), if we don't know how the test was done, it is often difficult to conclude anything.
One of the reasons why using the prefixes CI and ISO means the testing adhered to a methodology.
