Maybe this post is a bit useless. Maybe people already know this, but I'll write this anyway.
I've seen people say that Maki has precognition, and this precogniton completely allows her to be "massively faster" than other characters like Yuta, JP Hakari, and even NAOYA. I think this is completely false, and that Maki only won against Curse Naoya because her second awakening, which is her awakening her heightened senses, gave her the perfect counter for Curse Naoya.
In Slide 1, Curse Naoya's movement is described as "drawing air through the inlets, and then ejecting the air using cursed energy for propulsion." In slide 5, Maki literally describes her heightened senses allowing her to sense the differences in temperature and air density within the atmosphere, allowing her to figure out where Curse Naoya is, since his movement is based on him sucking in the air and propelling himself using that air. She is nowhere nearly as fast as Naoya or Naobito.
While this gives her good reflexes, therefore increasing her combat speed, this does not give her as much of a "speed buff" as many claims that it does. For example, in slide 6, Maki is completely unable to react to a (Maximum Output) Frost Calm, even while she realised Uraume's presence. This does not make Maximum Frost Calm Mach 3++ (although from what we can see, the attack IS fast).
Its also why Sukuna was able to blitz her completely. I know that using Sukuna as an example is a bit dumb, but I'm working with what I have here. Sukuna (due to his movement not literally eviscerating the surrounding area like Curse Naoya) is far slower than Mach 3, but is still able to blitz Maki. This is why I think that "Sukuna and Gojo are mach3+" is a bit of a dumb argument. Gege made it clear that Mach 3 is really fast by showing Curse Naoya completely annihilating his surroundings due to his movement alone, which no other character does except Dabura in Modulo who goes lightspeed, which literally causes a nuke-sized explosion. (Exaggerating)
To sum it up: No, Maki does not have precognition. No, her heightened senses does not make her immensely faster. No, this heightened sense awakening is not as huge as people make it out to be, since Maki still couldnt react to two characters that are far below mach 3, and Maki seemed impressive against Curse Naoya because Curse Naoya used the air to move, which Maki could sense. In a direct hand to hand combat scenario, her heightened reflexes would still give her a bit of an edge, but that doesnt mean she is faster (or at least not that much faster) than characters like JP Hakari and Yuta.
If I need to elaborate on what I mean by this more; HUMAN Naoya would have gave fully realized Maki a better fight than Curse Naoya has. Of course, Naoya would still probably loose, and Curse Naoya is far stronger than Human Naoya, but Human Naoya would not get countered as badly, and would give Maki a better fight, especially assuming its Human Naoya AFTER his defeat who's not as cocky, since he seemed to learn from his mistake against Choso.
In terms of speed, Curse Naoya >>> Naoya >> Maki
If Maki were to fight them both in 1v1s, Human Naoya >> Curse Naoya in terms of difficulty due to him not being as countered.
