> Most layouts were designed for English
Dubious. I don’t think the author even knows how many Japanese keyboard layouts there are, most of which are undocumented in English. They only discuss the letter frequency of written English because that’s the focus of the document, which is fair. They should just say so, without including an irrelevant claim like this.
