Not sure what you are even bitching about, exactly.
We aren't talking about some minor dramatic exaggeration here. We are talking about borderline superpowers and not a vague hint of resemblance to the real sport in the whole series so far.
Moves are off the mark, stances are wrong, commentary is from Fantasylandia and we have a guy with weeks of training competing toe to toe with a heavier nationally ranked pro in the first chapter, then another one with NO TRAINING WHATSOEVER but super-human reflexes blasting people meters away with quick jabs in this one.
This isn't about taking small licenses from reality. This is fucking Dragonball-tier bullshit. At this pace they will float around and shoot their fucking kamehameha by chapter 20.
Not to mention that even once you put the real sport aside what remains isn't exactly quality narration either. It's a bunch of hyperbolic shit that feels like a 14 years old fanfiction.
And yes, I've owned and managed a boxing gym for the last 8 years of my life, so I love boxing and I care more about seeing a somewhat decent representation of the sport than reading superpower-centered fanfictions.
Not sure why that makes you menstruate with anger, but that's just your problem and you should deal with it.
