How can scores from the same fight be so ridiculously different

So what would be the formula?

 

There are many different variables that play a part in it, but, imho, the biggest is that the scoring criteria aren't nuanced and elaborate enough, hence the anomalies.

It is up to commissions to interview and evaluate the judges and hold meetings and conferences accordingly and amend rules where necessary. However, from what I see is that the Bodies' Rules rarely get amended and they continue to use the same three/four (outdated?) general rules which are, imho, proven to be too vague given all the controversies.
Of course, one could also simply argue that DeLuca DKSAB.

This is from the WBC:

Basic Fundamentals for Scoring:

A. 70%: Effective aggressiveness is the most important factor for winning a round. The scoring of clean punches with power, number, and accuracy, whether moving forward, backwards, boxing sideways against the ropes or counter punching.

B. 20%: Ring generalship. If an advantage is not found in A, whoever dominates the round with boxing skills to control the action and does not allow his rival to perform.

C. 10%: Pure aggressiveness. If in doubt at the end of the round , it must be scored in favour of the aggressor, the one who goes decidedly after his rival, who forces the action to win the round, against a boxer who only runs away and does not stop to fight.
