You're referring to his fight against Danzo right? Not a fair comparison considering that before sick Itachi pulled out his susano'o he did the following: Used 2 Karasu Bunshins and sent them to Sasuke and Naruto before Sasuke reached the hideout; he then used genjutsu 3 times against Sasuke; used another Karasu Bunshin; then Tsukuyomi; proceeded to use Katon: Gōkakyū no Jutsu twice; then used Amaterasu twice on a pretty decently big scale. Yet Itachi was still capable of mainting all levels of his susano'o for a fairly long time, and then even still had enough in him to use a fuinjutsu on Sasuke to plant his Amaterasu into him.
-How much time was in between Sasuke reaching Itachi and starting the fight and Itachi sending out those clones? I'm pretty sure he had ample time to recover whatever chakra he used up on those two clones.
-He used 1 regular Sharingan Genjutsu, and then he used Tsukuyomi. He never used Genjutsu 3 times.

That's the end of Genjutsu 1, and this is the beginning of Tsukuyomi.

There's no Genjutsu battle after this, and everything before page 16 of 386 was one big Genjutsu battle.
-Yup. He did use a Crow Clone.
-Did use 2 Amaterasu and 2 Katon.
But after hat, the MS techs being the most consuming out of all the jutsu he managed to have Susanoo up for 5-10 at most.
Sasuke used Genjutsu against Danzo twice. He used Amaterasu while holding Susanoo up. Before that he had his V1 (briefly) and V2 Susanoo up. Then he summoned his hawk. After Danzo

of this sequence, I can say that Sasuke had his up for a good 5 minutes. Not including everything that happened before. Then he hit him with a Chidori Spear and a Genjutsu. And he still had chakra left, albeit not much. While Itachi used Amaterasu, Tsukuyomi, a crow clone, and a regular Genjutsu beforehand, the main things that'd consume chakra are the MS techs. Who knows how much crow clones use, but I don't think it's anywhere near 50%. Susanoo should use more, and that's what Sasuke relied on practically the whole fight.
I think the most important thing to be noted is that Itachi used 3 bunshins in that fight, as well as 3 MS techniques before revealing his suano'o. Karasu Bunshins was stated to take less chakra then Kage Bunshins, but they're still bunshins nonetheless, and are chakra taxing. Tsukiyomi and Amaterasu is self explanatory. I believe Itachi's stamina feats surpass Sasuke's.
Itachi used 3 Crow Clones, but like I said above, I'm pretty sure that the time in between Sasuke finding the fake clone and Sasuke meeting the real Itachi should be more than enough time to recover that chakra. Even more so considering we'd be measuring the moment the clone was used, to the moment Sasuke arrived. It's not like Itachi did anything.
