Basic more of a bunch of head canons.
Nothing suggests Zoro used Adv CoC and not even KAIDO mentions that, pretty much just dumb reasoning to believe a guy has a Advanced version of something he doesn't even knew he had.
We know for
sure only that KAIDO, Luffy, Roger and Whitebeard can use it because either Luffy confirmed KAIDO using or we could see it by Oden's and Law's reaction when Luffy literally did the same stuff they did.
Won't reply further because it seems you have already set your mind on this headcanon, only to be debunked later.
Yeah keep believing a guy that has basically awakened his CoC rightnow and doesn't even know he had is using a Adv version of it. Because that makes SO MUCH sense lmao
