In previous threads I presented analysis for HW and LW champions. All HW champions fights - who are the greatest MMA HW champions? LW championship timeline Here I will do similar for FW, BW, FlyW. I will start with graphs that show championship bouts for the latest time period ( 2009 - 2015). For FW and BW we have continuation of the belt from WEC (yellow) to UFC (orange). WEC didn't have Flyweight division, so I included Shooto and Tachi championship bouts.
