Of course :)

No single number would ever describe the speed of something as complex
as a python interpreter (unless the number is 42 of course). However,
there were request to reduce it to that and here we have one. I don't
think "4x faster now!" is a good marketing slogan even. What's
significant however is that it's getting faster with each release.
