How is the reach calculated? If it's just a sum of follower numbers, it will overestimate due to duplicates (eg http://blog.ouseful.info/2012/02/09/what-is-the-potential-audience-size-for-a-hashtag-community/ ) let alone the fact that many followers in the follower counts will be bots, dormant users etc, and the few that remain probably won't see the tweet anyway...


Very good point Tony - short answer is that I don't know. I suspect that if I was going to pay them money it would be one of the questions that I asked first though! :)
