People can try and pretend that there is a formula for judging boxing and that Judges are highly trained individuals, its all bullshit you can sit and watch a round and decide who won making it 10-9 for your pick and adding up any point deductions. You or I are as a good a judge on the pro level as any pro judge is...probably better.
Who ever hits the other guy more without getting significantly hit in return gets the round. A knockdown usually wins the fighter the round by two points, and more than one knockdown without a KO wins the round increasingly by points per knockdown.
For me, it would be much easier if i knew both fighters well before i can score and judge the rounds and the winner.
