For this statistic, we used the organization that fighters last fought in, unless a fight is scheduled (that we have in our DB). The one thing I did do, is separate the 18 fighters who the UFC recently cut (Fitch group + Nunes and Vieira), into their own category. We left out the StrikeForce fighters who do not have a fight scheduled in the UFC yet.
