I don't have a dog in this discussion, but the question prompted my interest in finding out the average length of time for all past UFC champions between them first winning the title to their first title defense. I count first titles only (Couture at Heavyweight, but not at Light Heavyweight). Interim Champions are not included, with the exception of Arlovski as he was later promoted to undisputed champion. I also did not include WMMA due to the lack of depth in their divisions, which would make this an apples to oranges comparison. I also did not include Aldo and Cruz as they were promoted from WEC champions to UFC champions.
