Mixed martial arts is just over a year into a new, more liberalized criteria for 10-8 round scores. Approved at the 2016 conference of the Association of Boxing Commissions and Combative Sports (ABC), the new criteria officially went into effect on Jan. 1, 2017.
A 10-8 round continued to be defined as a fighter winning by a large margin, but the written guidelines for these potentially difficult decisions expanded from a single sentence to more than a page of explanation.
In practice, judges used to use the then-unwritten two D’s of 10-8 rounds: Domination and Damage.
