How Much Does Striking Even Matter To MMA Judges?

It seems like some judges don't care about striking if they don't see an opponent's had snap back, bleed or if the opponent is knocked down.

Usman threw more strikes and landed more strikes. He won the silly "walk forward aggression" battle, because I don't remember him backing down from Covington, but I do remember Covington backing down.

And yet, one judge had it 3-1 for Covington. LOL
