> Regarding 2.7.13 - you might find it surprising, but it's actually SLOWER than 2.7.2, there has been no speed improvements and quite a few speed decreases, so we decided to keep the faster one.

I don't find it that surprising, but do find it disappointing that you would run benchmarks against the current version, but not post them online for perusal, nor provide any sort of explanation for the use of the older version in head-to-head comparisons. For me, at least, it produces the impression that PyPy has something to hide, and I doubt I'm the only one.
