You should count capacity (fraction of consensus weights), not number of
relays, in all stats like this.

Otherwise you'll end up falling victim to the same sorts of problems
many researchers fall into -- which ends with crazy statements like "20%
of the Tor network runs Windows, and everybody in the world can break
into Windows computers, therefore I can control 20% of the Tor traffic"
(if you'll recall that talk a few years back).

In this case, it looks like these are the summed consensus weights,
using the 2013-09-08 07:00:00 consensus:

Tor 0.2.2.x: 431869 (4%)
Tor 0.2.3.x: 5020458 (45%)
Tor 0.2.4.x: 5363503 (48%)
Tor 0.2.5.x: 256831 (2%)

If I'm counting this right, Tor 0.2.4.17 by itself is 3681624 (33%).
