Why the disparity in viewer scorecards?

Cringe

 

I tell you what can swing it, and ive caught myself doing this often.. and thats paying more attention to one fighter than the other. It can be quite tricky sometimes to give both guys the same amount of eye time. In fights where there is lots going on, i think the human brain struggles to compute and process all the information which it is viewing, regardless of how much you know about the sport. This plugs into the bias side of thing, as often you will pay more attention to your guy than his opponent
