Average is definitely the wrong metric to look at for this. It's like saying "the average speed of a car is only 25 MPH, but you're paying for one that can go 70", but everyone would probably agree that going over 70 is valuable even if it's only for short bursts. Especially bad is that graph of speed vs average bandwidth used (%). Of course people don't max out a 1000 MB/s line constantly, that'd be nuts.
