Unless a guy like BJM with some say wants to change the criteria, the 10-point boxing, this is how it's gonna be. Very difficult parameters for often inexperienced people to work with.
Of course if they'd have former pro fighters and coaches only the results would be better. Really regardless of criteria. Competence shows.
They could also show cards in between rounds. There needs to be clarity.
Also as said ITT the UFC would've done something about it, like with the sudden omission of some refs, if they cared enough.
