When estimating the number of recurring daily users, we divide the number
of locally observed requests by the expected share of requests seen at
that directory. The result is the estimated number of total requests in
the network. Right now, we're using self-reported request shares for this
calculation, but these numbers may be wrong. Only recently in May and June
2010, the directories report very low shares of 1/10 of the usual shares
or even 0.0%, which must be wrong. Rather than believing the relays here,
we could determine request shares that directories should see from the
descriptor archives. The descriptor archives reveal how many directory
mirrors there are and what bandwidths they advertise that are used for
load balancing by clients. The request share of one of the directories is
its bandwidth divided by the bandwidth of all directories.
