Oh and just as a heads up, for that tyre review site, they dont know how to use illustrative charts to properly show data. In fact, its dreadful and shows they have no statistical knowledge at all for example the charts here https://www.tyrereviews.com/Article/2022-Tyre-Reviews-UHP-Summer-Tyre-Test.htm
From your referenced article, with the multicoloured bar charts, I'm interested to know how you would display the data such that it is easily understood by a layperson and not out for peer revue!
What I like about the tests he does and the results, per your exampled, is that they are as close to a scientific test as commercially practicable and to test them they need to be used on a consistent surface, usually a test track. Whilst you state that these are track tests, this is agreed, however these tests types such as wet braking etcetera are relative and transfer well to road use. Doing these tests on a public road would be impractical and with the state of public roads, inconsistent. Yes these tests could be more accurate by increasing the number of test car types, plus more drivers, and with a longer test duration to promote more tyre wear data. Unfortunately, that costs significantly more money and not commercially viable unless commissioned by a tyre manufacturer which then can promote bias.
