>They're all unambiguously superhuman so it makes weight classes feel more arbitrary by default
Until they suddenly aren't though. Sandro likes to have his cake and eat it too when it comes to how and in what ways his characters are superhuman. You take them being superhuman for granted when Sandro doesn't want you to think of them that way. The lip service he pays everyone, from jobbers to the tippy top tier main characters, is to convince you they are just dudes who are just really good at what they do.
The issue is that PERCEIVED offensive capability tends to outstrip the human limit to take punishment in these sorts of manga.
Kengan constantly tips the scales back and forth. The manga wants to be "mostly" grounded by talking about weight classes, the limits of human perception, reaction speed margins, mechanical advantage, and the effects of pain on performance, but sometimes those things are just blown away by the characters shattering concrete with their fists or virtually breaking the sound barrier.
The main difference maker we're given is that trained people, geniuses, and freaks of nature just know how to use what they have better to "unlock" this earth-shattering power. Thing is, human durability doesn't really scale up that way, so what you end up with is a wishywashy end result where people shrug off ground-cracking blows to their faces and spines with some bruises, skin-level bleeding, and heavy breathing. You can't really visually display increases to defensive ability in the same way as offensive ability via environmental destruction. Trained fighters just have a bigger HP bar or more meat points before they actually take debilitating injury.
