There is a huge difference between the two examples.The Mullard example is taken from an "application note", as it is called today. The note is advocating a design practice that might reflect favorably to sales and use of their products (EL84 and EL34).
The WE table is taken from the datasheet and is illustrating the various operating points and loads recommended for the product in question. And it is very useful as such. Of course, those are just examples that should lead the engineer in his design work.
One must be very superficial to miss this distinction. Furthermore, none of the texts has scientific or academic value, and neither of the texts was ever intended to have. Marketing departments and general lack of knowledge have lead to some sort of canonization of "ancient" technical texts.
