After having a brief look at the your table, I'm very confused by this 
assessment:

To me, it seems that PyPy NumPyPy is equal or significantly faster than 
CPython NumPy on most benchmarks, but substantially slower on just a few 
of them.

PyPy NumPy is slower than CPython NumPy on all benchmarks, with some being 
not that bad, and some pretty bad, but this is absolutely to be expected, 
and in fact nevertheless very impressive, considering that it runs via 
CPyExt...

Am I completely misinterpreting your numbers?!
