How is that a fact that proves anything? Its not like he is 160 or jumped on scale so it has to bump violently to the top.
Fact is scale was locked when he stepped on it, so no bumping inertia (why? because when you step forward you use gravity and inertia so you weight more, same like jumping down on something, thats why scale bumps up when you step on it.) this is the reason scale goes slower up, and same reason why it wont be going up and down like Robs (mate you cant have both ways, if it slowly goes up it wont go down, if you jump on it it will go up-down)
2nd fact, at no time did that scale show 155 after being unlocked, and it was in most top position when turned off.
and the biggest problem isnt that he weights 156 or something. if he missed scale he would have to torture himself for 2h, he would shorten his recovery time and he would be physically weaker tomorrow, this is pure cheating on part of Khabib and UFC. this is worse then JJ picogram. JJ had less benefit from that pico then Khabib will have for not having to dump that 1lb. This is the problem.
