You can whack off a part of every paragraph and still make enough sense of these to understand how unreliable the explanations are.
A linguist might well ask (probably study) the minimum proportion of message that you must reveal in order to assess the value of it. Of course paragraphs of Shakespeare will return different values than a treatise on sore throats.
The lesson I draw here is that plenty of twaddle is freely fed, with a satisfying sense of authority (or mischief), into the internet. Look something up at your own peril.
