I would think this number can be highly massaged anyway.

I hate twitter but have an account I barely ever log into and have never tweeted anything. If you want bots to be lower then count me in the sample. If you want bots to be higher don't count me since I am not really active.

If you want bots to be lower then take the sample at 4am EST on a Tuesday of US users.

If you want bots to be higher take the sample right after a major news story breaks.

Instead of 5% you could say 10 million active bots a month to make the number sound higher too.
