Itachi is actively controlling senses, that's why he'd experience the dilation as well. Tsukuyomi is how he'd experience the dilation lol, he's the castor. So Tsukuyomi increases Itachi's own perception to 72 hours/1 second? I still don't see how Itachi being the castor of Tsukuyomi increases Itachi perception, just because Itachi is controlling their cranial nerve. We don't know if Itachi is actively controlling the illusion of Tsukuyomi, but your theory runs into a problem. Tsukuyomi increases the opponent's perception by manipulating their brain through genjutsu. Since Itachi doesn't manipulate his own brain through that genjutsu, than it should be impossible for him to increase own time perception through Tsukuyomi.

Being the castor shouldn't change that.

Black Zetsu has been around since Kaguya, he probably can recognize the technique from when he's seen Itachi use it before. Itachi may have been the only one who could use Tsukuyomi. How would Zetsu recognize, with 100% certainty, Itachi's using Tsukuyomi? As far as Zetsu knows Itachi could be using a different genjutsu.

So you think their Sharingan lags behind their perception? But their regular eyes keep up with the increased perception? Lol what do you mean? They experience all 5 senses being messed with. If Kakashi is looking around in Tsukuyomi and sees all 72 hours of the events within a second, his Sharingan is there too. Kakashi's processing speed has been sped up. All of it. His ability to feel pain, his ability to think, etc. His Sharingan isn't suddenly exempt from it. He's looking through his Sharingan. It's not their eyes that are seeing in the illusion, it's just an illusion. Kakashi wasn't even actually seeing multiple Itachi's stab him in Tsukuyomi, because in reality there was only one itachi, he didn't even have sword. It's just like when were dreaming, our eyes aren't actually seeing monsters and whatever were dreaming about, it's just a dream. It's a similar principle with genjutsu. Our eyes are closed as well when were dreaming so we can't be seeing anything.

Also I don't think any Uchiha can break out. Only the most skilled.

What Kakashi said to Chiyo is irrelevant because they aren't Uchiha. Chiyo said they could break each other out of Genjutsu by disrupting their partner's chakra. However, it doesn't matter if Chiyo could disrupt Kakashi's chakra or not; he'd be hit with the damage before Chiyo got there. That's why he said it didn't matter whether they could defeat Genjutsu or not. Because the victim is the only one who could possibly break it, and they have to be an Uchiha to even stand a chance.

What Kakashi said is relevant. He implied even if it was possible for Chiyo to break Tsukuyomi, that whatever method she uses, won't work because she won't have time. So even if Chiyo could break out of it on her own, if Tsukuyomi was longer, it wouldn't make a difference, because it's over before she could break it.
