How is a boxing match actually judged most of the time ?

[WillieWild114]

I thought the winner was the Boxer who was able to outland his opponents in most rounds apparently this not the case all time. What makes judges give the some boxers the UD or draw despite being outlanded most rounds

there is criteria for scoring a round

then u have judges who will bend over backwards to get the A side over the line or a draw if they cant get a W for them
