Luffy still doesn't seem line he's using CoC consciously
It's different to Zoro who when Luffy figured it out said and I'm paraphrasing it seems Luffy figured something out implying Zoro didn't know what it was.
Luffy is using AdvCoC on the same level as Kaido, Big Mom, Shansk Roger and Whitebeard etc.
Zoro is roughly on Yamato and Oden level of AdvCoC unable to split the skies but attack with it.
