So quite accurate then, since 11Mb/s = 1.375MB/s.

(The conscious mind, of course, is not where most of our learning from experience happens.)

I am very suspicious of the numbers and statistics quoted in this article, as there are no references cited for their claims, and no indication as to how they arrived at them.

That doesn't sound accurate. The human eye's resolution is in the tens if not hundreds of megapixels [1] with high sensitivity (meaning the compression isn't very lossy so the bits of information remain). Even if you assume only a few frames per second that's far more than 11 megabit/s.
