Maybe I am a bit confused, but I don't see a difference between those  
two things?

i.e., if the speed is 0.8x CPython, to me that means that it runs in  
80% of CPython's time (i.e., faster), whereas 2x CPython would be  
twice as much time.

In any case, I agree that the second formulation is phrased more  
clearly, just curious if my understanding of 0.8x is flawed.
