I don't think people are understanding just why this shit should be immeasurable.
IDK why tf shiz like OPM get mentioned here, but from the example I saw, it's more than likely Non-equivalence fallacy and is nothing close to wtf is going on here. For 1440 to be a threat to TBD in any meaningful way, he would literally have to have Immeasurable speed in some way, otherwise, regardless of how strong the attack is, it will never ever hit TBD, and will never be a threat to it regardless of how severe the hax is.
Just, think of it at a logical point, how can you ever be a threat to something that is beyond time, can move through time at will, and literally sees anything less than immeasurable speed as frozen? Anything less than Immeasurable speed will never affect TBD.
Like, you can at least argue for "Possibly"
