The public numbers advertised were 13M _IPs_ connecting to a sinkhole over more than a month's time.  When I've had visibility into other large botnets (srizbi, rustock, mega-d), I was consistently seeing a 10 to 1 IPs-to-unique-bots count over a time period of a week.  Happy to make the raw pcap data available to anyone who is curious.  The UCSB guys showed similar results in their excellent Torpig paper.  http://www.cs.ucsb.edu/~seclab/projects/torpig/torpig.pdf

My unscientific finger-in-the-wind would put it at well under 1M when you are talking a month and a half of monitoring IP connections.
