"2.7 Browse a responsive web site" makes incorrect assumptions about rwd

The doc says:

John is en route to his dental appointment. He is late, does not have a record of his dentist's phone number in his mobile device's address book, and has a very poor network connection. Fortunately, the dentist has a responsive Web site which displays with minimal use of resources on John's mobile device. He is able to find his dentist's phone number and call her.

The above makes a flawed assumption that RWD somehow equals less data. Evidence shows that only a very small number of rwd sites actually result in smaller d/l for users (6% had significant savings, while 22% had slightly smaller size). RWD is mostly just used to adapt layout, not reduce the size of content.
