You don't know what unfair means then.Most refs do not take a point for a second eye poke. Some don’t even take a point for the third.
A competent ref follows the rules. The rules literally say you go to the scorecards if 1/2 of the fight is done.
A unfair biased ref instills his own rules.
The rules were written, published ahead of time, agreed upon by Silva and Weidman, implicitly if not explicitly signed through contract.
They both agreed that if an eye poke was going to end the fight after 1/2 of it occurred, they would go to the scorecards. That was written before head.
The book was agreed upon.
