Kaido is now weakening
Not that he was weakened!
And he started to weaken only after fighting Yamato 1v1
So Yamato is the final nail which triggered Kaido's health and powers to weaken
+ KAIDO exerted more efforts vs Yamato as he was even enraged into trying to make her understand
nowhere it's "Kaido is weakened"
Yamato is indeed the one who pushed kaido to start to weaken. If Yamato didn't fight Kaido, His papers wouldn't be weakening this soon.
Zoro, Kidd, Luffy ...did damage but it wasn't stated that Kaido was weakening back then post SNs battle
