Further edit in response to the reply below, which is too deep to reply to – In the interests of brevity, clarity and sticking to the subject, the entire process used to test the modals was not included in the article.

There's plenty of things worth arguing about in the piece, lots of it is pure opinion, and some of it is probably plain wrong so it seems a little odd to pick that bit as the thing to take issue with. Maybe I should have been much clearer about the testing process.
