These kinds of stats are always flawed. In a lot of cases, they're
skewed heavily by defaults, and in other cases, skewed even more
heavily by long dependency trees - so, for instance, a single Django
installation might involve fetching large numbers of packages from
PyPI, even though no new code has been written at all. Might add quite
a bit to the download stats for one version or the other. And what
about upgrades? Stable installations are still likely to want to get
the latest, which means downloading from PyPI, ergo it's another hit.
