Experience and skill are still part of Zoro's intellect. Reading the opponent's move is something that all expert fighters, swordmen and such can do even in real life, it's part of general skill, we just can't give it to all characters because they supposedly can do it. Zoro has demonstrated it, but just like technique mimicry we can't just scale that stuff to other comparable characters, otherwise Vista too gets it for being more skilled than Zoro, Shanks for being equal to Mihawk and then all characters that are better than Zoro.
We can't be sure, it's a specific type of skill that Mihawk might not possess
This is a non-thing, because other verses being wrond don't make this good.
His style being superior to Zoro's doesn't make him skilled in the same specific style. If we assume Mihawk can do everything Zoro does, including intellect-based things, that we have to assume he could wield two swords and one with his teeth and all the rest. We just don't scale skill in this way, the only exceptions are plain statements like "X can do everything Y does" or similar.
It was an example, Mihawk being more skilled than Brook doesn't make him more skilled than him in the same style. But it was a random example, a karate pratictioner might be more skilled than a pugilist, but it doesn't make him better than him in boxing. I meant that being more skilled than someone else doesn't make you able to replicate every single thing the less skilled person can do.
It's never stated that he knows every existing type of swordmanship, technique, maneuver and so on, he is indeed the most skilled but he isn't an omniscient swordfighter, he is """just""" incredibly good with his styles. And again, if Baki and Kenichi are wrong they are wrong, keep out the other verses.
