One thing I've noticed about advanced CoC is that despite many characters having it, we've seldom seen them use it. I mean shanks OBVIOUSLY has it and he never used it against whitebeard, who we know has it.
Whitebeard never used it in marineford, big mom never used it in whole cake island, and while kaido does have it, he only uses it in special attacks(ex. thunder bagua and ragnaraku). Kaido mainly uses advanced CoC as a finishing attack, not as a casual tool.
So what if advanced CoC has some sort of timelimit or drains haki faster than CoA or CoO? This would logically explain these discrepancies, and it would prevent advanced CoC from becoming an overpowered ability. It also explains why Luffy lost against kaido despite seemingly being on his level the last time we saw them. Luffy lost because he relies on his advanced haoshoku too much. Without it, he isn't on kaido's level.
Also, if asura is an advanced CoC technique, then this would also make sense. As zoro can seemingly only use asura for a short period of time and he only brings it out at the very end to finish a fight, quite similar to thunder bagua which is one of kaido's finishers.
