Hi LLuis,

As Sean already said mirrors are not included in the stats. The
monthly nb of distinct IPs are reset every month and the yearly
nb of distinct IPs are reset every year.

Some packages are indeed in two categories. Category assignment is
based on the download URL only. For some mysterious reason the Apache
logs contain some lines that indicate that AnnotationDbi was downloaded
from an URL that points to a data experiment repository. These lines
are very rare though (1 or 2 per year) so overall don't have any
significant impact on the stats. Anyway that's something we'll need
to dig into at some point.
