It's not, people iRL can actually attack at what we rate superhuman speed, tho their reaction is lower than 0,08 s.
I meant reactions are faster as in they come before movement of the body. Reactions is the time it takes before your body reacts/responds to stimuli. Followed by movement. If a bullet blitzes your reactions, you're def not gonna be able to move to counteract it. Plus, you can't really compare reactions to movement speed because one is a speed and one is a timeframe.
Assuming we have two scenarios where both involve a gun which can shoot a bullet at 400 m/s and a guy, the distance gun - guy is 10 m, the guns shoot, the first guy can react when the bullet cross 2 m meaning his reaction is 2 / 400 = 0,005 s, the second dude can react to the bullet only when it crossed 9,999999999m meaning his reaction is 9,999999999 / 400 = 0,0249 s which one is more impressive? The one who noticed it when it was 8 m away or the one who noticed it when it was 0,00000001 m away? The distance he traveled is irrelevant especially when in that specific context it doesn't really look lke he moved a dozen of meters, he made a small dash of 2 m at best and the bullet was right in front of him.
The issue is you're assuming the guy can ONLY react after the bullet traveled 8 meters. When it could be a conscious decision to wait until the bullet is close among other possibilities.
Which is more impressive, the guy who reacts to a bullet that is 9 meters away, or the one who chooses to react when the bullet it 0.0000000000000001 meters away? It's the latter. By far.
I talked about reaction and not movement speed, they are different, tho I agree that if you run at a certain speed or you react while moving you body it also count as reaction sure but in this context is him moving the head a distance similar the distance the bullet traveled when if he was actually 440000 m/s he could have react to the bullet, go and take a coffe and return back and the bullet wouldn't have moved.
Dodging a bullet from point-blank (cm away) would be combat or reaction speed. If your reaction/combat speed is far faster than a bullet, then your reactions will default be able to pick up on a bullet. You're never gonna see a dude with MFTL+ reaction/combat speed ONLY be able to react to light when it's 1 meter away from their face. That's clearly just them choosing to only react when it's close or not taking notice of it for other variables.
If a bullet is 1 cm from my face, and I travel 100 meters to dodge it in the same time it takes the bullet to travel that 1 centimeter, that would mean I'm 10,000x faster than the bullet. My reaction speed is not gonna be 10/343. How could I possibly make a MHS+ movement but then not have reactions that scale to it? That's what I'm getting at.
Yeah I pointed that out, the problem is that the distance the bullet move and the distance he moved are more less equal and we are talking about a Massively Hypersonic+ dude, that bullet should literally be frozen compared to him, small size it's an excuse to a certain point.
That's fair enough... but you could also just interpret that as him actively choosing to take the shortest method of catching the bullet. Just because he's far faster than the bullet doesn't mean he has to statue it and go out of his way to run 20 laps around it and then catch it with his hand and place it behind the dude who fired it. He coulda just decided to catch it with his mouth and that's it. And small size is a fair excuse when you consider he was running after someone around a corner in the linked scans. If I'm running around a corner, and I come face to face with a tiny projectile, I might not notice it at first. I'm preoccupied with chasing a guy and taking a turn.
In fact I was ok they are faster than bullets, my main point is that the difference in speed isn't that great, if there are more instances which gives more support to the fact they are massively faster than them I'm perfectly fine, I just pointed out in that specific scene with the same Massively Hypersonic+ guy the difference in speed between the two elements is nowhere near what's presented in the OP, especially when it's a direct statement and not even a calc, I kinda calc it and found out a 390 m/s result with the bullet being 400 m/s and all i said is that it's weird, these dudes are geniuely faster than bullets thought not in an absurd degree, I'm saying that.
Which is fine, but the dude choosing to react to a point blank bullet and not choose to blitz it isn't an anti-feat. It's just the guy deciding he'd rather catch the bullet with his mouth than run laps around it. Not everyone is into theatrics like that when they're far faster than something. If he noticed the bullet and couldn't react to it at all, that'd be a perfectly legit anti-feat. But someone faster than a bullet catching a point-blank bullet with ease isn't an anti-feat. The same way someone casually slapping away a beam of light 1 meter away from them isn't an anti-feat for a MFTL+ dude.
I wasn't trying to say you are fully against MHS+, but I disagree with this being a valid anti-feat. A person with MHS+ speed would also be able to easily replicate this feat if they decided they wanted to catch it with their mouth.
