It will probably be a few months real time as the drama builds up.
With the SNs stalling and doing no real damage to Kaido but people claiming Zoro is amazing.
They claimed it when he helped wipe some dust and debris from kaido's clothes with Killer, they claimed it when he was dodged by the slow Kaido (after Big Mom recommended it- he wasn't going to bother), if the spoiler provider has exaggerated again and this attack doesn't do much damage or is merely compounding the vast damage the gattling did, they'll still claim it as a full win to cause some cuts to Kaido that he'll probably heal instantly (I doubt Oda is going to sully Kaido's hybrid design too much).
