Just nitpicking here, but you shouldn't forget that any given set of 
benchmarks can only ever be an arbitrary one. If you change the current 
set, you can rightfully make any claim from "PyPy is 100x faster than 
CPython on average" to "CPython is substantially faster than PyPy". Taking 
the average is a nice addition right below the graphs on speed.pypy.org, 
but makes no sense at all without this context.
