Grading on a curve in a nice way to describe whatever it is The Verge does

Let me understand something.
If the one major downside to the Samsung Chromebook 2 is the fact that it’s “too slow to really get anything done,” how the fuck does it get a 7.6 score?!
That’s like dropping a four cylinder, 92-horsepower engine into a Ferrari 458 Italia and saying it’s “too slow to really race against other sports cars,” but still giving it a 7.6 score of of 10.
I don’t get it (and this isn’t the first time The Verge has posted wack reviews).
