I think destroying a structure like Low 2-C or 2-A would have an Immeasurable attack speed, since all points in time from the past, present, and future moments would need to be destroyed, except for maybe special or rare cases of provable time-traveling attacks.
Sign.......While i understand this, but seriously through the entire thread i never once said DBH character are all 2-A thus they should be infinite, or immeasurable. That logic is extremely flawed, bad and low content and i agree that it should not be used. However thing is more than just ragen and AP
Just destroying something like the present or present moment of a Low 2-C realm would have at best Infinite (attack) speed assuming the realm is infinite.
In most cases, these feats are treated as range feats especially since these feats tend to be outliers or have inconsistencies with the characters' speed.
I am uneasy about scaling the speed especially if the feats are largely outlierx or inconsistent with other types of speed from lack of major supporting evidence.
1. That is the main thing, the attack capable of infinite speed due to it spread across the infinite multiverse in finite time and character reacting and scaling to it. DBZ, DBS was already confirmed character capable of reacting, dodging, etc......to the blast and explosion that capable of spreading, covering the area that comparable to their range (DBS is 3-A AP and range). So by all mean DBH (and DBZ, DBS canon to DBH) can also do the same, can react and dodge attacks or explosions that cover infinite sized structure in finite time, or infinite speed attack, explosion. And it it supporting for other main evidences
Black Hole from Mechikabura is just slightly opposite, it pulled everything into itself rather than exploding. Due to it can absorb infinite sized structure, it must pull everything with infinite speed into it, or else most of the multiverse will never be absorbed due to incapable of crossing the distance. Character like Chronoa, Trunks reacted to objects flied at infinite speed to the black hole so they still qualify, especially Trunks who being pulled at infinite speed, he reacted to his own speed, by all mean they are qualify. Pulling in or Spreading out is just opposite direction of movement it doesn't determine speed, speed mean they physically move, through a certain distance/length with a certain time, in this case objects and character move at infinite speed due to infinite length and finite time
2. Mechikabura is the Black Hole itself or a part of his body, i and OwO already pointed it out in this thread and in the sandbox, and it boost his overall power up (actually alot), which is ki/energy, we all know that ki boost in DB mean ap, dura, and speed altogether, the Black Hole have infinite absorption speed, Mechikabura by all mean can scale to the Black Hole itself, they are one. Both game and manga repeatedly said Mechikabura become one wotj Black Hole that absorbed the entire multiverse. And to support this point Mechikabura also said he have infinite energy (kinda) due to absorbed time itself.
3. Demigra's Light Chain cross an infinite sized Black Hole to catch and pull Chronoa, Xeno Trunks,.......out. However Planck also uncertain about this feat so i understand
Outlier is out of the question. The reaction speed was repeatedly confirmed multiple times in DBZ and DBS. This time with DBH it is just a larger scale, there is also the Fu feat which i forget (admitedly) to write in the sandbox which is in the OP, that character consistently reacted to absorption, sucking/pulling speed, one character even capable of performing his move to keep two others character from being sucked.
Inconsistency is not either, unless we talk about how to show infinite speed visually on page or video. Which if we go with this logic then many verse suffering the same, infinite speed and immeasurable speed always being inconsistently displayed visually
