lack of self esteem is a real pain in the a-
Let me explain why I.R.I.S.' Analytical Prediction is superior to Mash:
1. It allowed a very below average Ali with no combat experience and weak physique nor any familiarity with I.R.I.S. to avoid ground-based shockwaves (4000 m/s in bricks) which is borderline impossible to do as a normal human.
Not too impressive, actually. If we wann talk about avoiding shockwaves or anything similar, Mash has already done something, well, similar. In his fight against Margarette Macaron's true form, after being struck multiple times by attacks that were faster than himself, suffering internal damage, and forced against a wall, Mash was able to dodge the attack by simply putting his hand against said wall and feeling the early oscillating sound waves to avoid Margarette's next attack.
2. Overwhelmed Uno with Pre-Data Erasure Override Mode even though he was
speedblitzed by him at such speeds that even I.R.I.S. that has FTL perception didn't manage to process or perceive his movements.
That's cool, but Mash also manages to fight on against those that speedblitz him heavily with his own skill, such as against Abyss Razor who had a great speed advantage against Mash. This is why it's always important to bring up Mash using the environment to his advantage, because if someone is faster than him he will limit his opponent's potential to move, such as splitting the floor in half.
Again, if you want to be a math wizard, this would be great. Unfortunately math isn't going to help much here. Plus, what's so advantageous about reaching a state beyond the normal human capacity? That's just normal Shonen skill.
4. Zain, an agent who in a single moment could
accurately predict and counter his opponents actions in a blink of an eye is initially unable to overcome Uno's Analytical Prediction under the influence of Override Mode.
Oh hey, those were some nice visuals. Would have been helpful if we, you know, didn't see him fail at this analytical prediction?
The internet archive won't load for me, but if Iris is anything that Zain fellow showed it isn't that impressive. And being outnumbered isn't that great of a feat, the stamina part is, but taking on groups of people isn't. Mash is comparable if not superior in skill to Visionaries and his buddies, who were able to hold off an army of double-line level monsters.
That's cool, fighting someone with overwhelming stats over you and winning, but again that's something Mash already does. He grows and overcomes his opponents despite still holding back, and just won't go down, because he's Mash. He can't afford to give up in his story, so he fights on. Also, again, I'm forced to go by your own word because the Internet Archive won't load the video.
Ali also only needs to attack mash repetitively to beat him in this fight due to 6-C damage accumulation of which he has plenty of options to achieve that goal.
And that's the problem, despite all those options, Mash's growth rate is just insane. Again, he only needs to see things once for it to be played out against him. And if needed, he can jump to gap between him and an opponent despite a wide difference in power quite quickly by just developing. Such as when he was forced to train against a hundred armored knights. Plus, it's going to be really hard to slow Mash down, he eats tens and tens and tens of his own punches, having the damage transfered back to him, like it's nothing.
