What day did the 10-8 criteria get changed this year?

Which was the first UFC card to use it? 

didn't realize there had been any official change...

This may be only in california. As far as I remenber all this talk about changing the 10-8 criteria began in bellator dynamite, which was held in Cali, when jimmy Smith explained that Big Jhonn McCarthy told him about a change to the 10-8 scoring criteria, for california only? Idon't remenber. Jimmy explained what Big Jhon told him, basically a 10-8 would be scored for a dominant round and that you don't necesarily have to come close to stop your opponent as long as you control/dominate the whole/most of the round. However, Jimmy wasn't even sure if this new criteria change was official. There was a draw that night, in which a dude won a rd 10-8 for taking the back in a standing position most of the round, then the dude lost the next two rounds and it was a draw. Jimy said something among the lines "that if the new criteria is applied the 1st rd. was 10-8 and the dude lost the next two rds. 10-9 so the fight would be a draw" and the fight was actually declared a draw 28-28. I don't like this. If there is a rule change they should have made it public with the media before instating it. If someone could go back and watch it, that would be good. I think It was in the first prelim (the only fight that was a draw) where it was explained this rule change.

my understanding was there wasnt a change- california has been looking into ideas to improve scoring for a while, including half points being trialed in amateur bouts but that all thats happened so far for pro bouts is a clarification of the existing rules reminding judges that not every round is a 10-9, that 10-10 and 10-8 exist (and shouldnt be super rare)
