That's exactly what I'm talking about when I talk about "scoring in Brazil". Not the judges, but the fans. In most Brazil arena events, the fans usually go pretty wild for any strike a Brazilian fighter throws or lands, etc which could possibly influence scoring.
I don't know if it was just me, but for this past stadium event, the fans didn't seem to be anywhere near as loud as they normally are. I'm assuming it was because the venue was a lot larger than a normal arena. I'm not going to say that that was the concrete reason why the Barb fight wasn't at least a split etc, but I think it could have had something to do with it
