So you put aside the Akainu tanking feat from my post ?
I knew you would said that : Ace and Jimbe were fighting at low high tier level. Aokiji and Akainu were fighting at top tier level and landed top tier hits on each others. And they lasted 10 days. This is an endurance feat.
It doesn't matter, what you want to show is endurance, the endurance of fighting for days against an equal. I used ACE and JINBEI to show you how wrong you are. Also, you're using higher-level off-screen attacks, as if AKAINU and AOKIJI are hitting their finishers at each other all the time.
AKAINU and no admiral is KAIDO, no other upper tier has recovery, which means that if ZORO hits his opponent, the opponent I will call X will be injured until the end of the fight, that is, if he resists, and that will impact your performance, because whether you like it or not it is a very relevant blow in AP, as it is an injury that may need urgent medical treatment, so don't go with common sense thinking that others are resisting it better than KAIDO, the others will suffer the consequences of the blow all the time while KAIDO will not.
