Absolutely not. You're literally making shit up, in none of these fights, NONE OF THEM, has Kaido demonstrated any advantage in Attack Potency.
Against Oden.

Against Big Mom
I've read through all these battles. Where's Kaido blantant AP advantage? Nowhere.
Doesn't matter. They still scale from hurting him in a very visible manner.
Not making a life-lasting wound isn't a factor on either someone scales to Kaido or not.
LOOK AT THAT. How is that not enough for them to scale? (Obviously, they did that much damage with 4 of them, so they scale to 1/4th of his AP, not full on)
Scabbards aren't fodder, you are literally ignorant about One Piece scaling, because you have never read the manga. You brought your ignorance to a CRT, an actual serious subject that's going to affect the verse here. Please, please just quit trying to fit into a verse you know virtually nothing about, you're being quite the annoyance.
You know why we don't scale Marine fodders to WB's durability?
Because "WB" wasn't known from tanking hits.
Narratively, his durability was never even a subject matter for the story. (Au contraire, his AP was)
Whitebeard was, old, sick, couldn't use Koka, and was again, portrayed as a stamina monster (for taking so many hits).
The Marine fodders have shown to be overpowered by Town level character, likewise being weaker than them in power, scaling them to WB would obviously mess with the scaling, thus, them hurting WB is a Plot-Induced Stupidity, and an outlier.
None of that applies to the scabbards. Go sit in the corner.
The "actually" doesn't exists.
Kaido was just surprised that a kid who couldn't even scratch him, and couldn't even use Ryou (before the rooftop) was damaging him WITHOUT A SWORD (aka, why it's even drawn attention to the fact he damaged him with a physical blow) not that he wasn't damaged before.
Again, something you would know if you weren't completely clueless and ignorant on the STORY of OP.
Because the singular damage Luffy did was superior to the scabbards by a high amount, to the point where he could realistically fight Kaido on his own.
Not a case with the scabbards. Doesn't mean they don't scale to 1/4 of his AP individually.
Also, they made Kaido scream in pain
First, the Boro Breath doesn't have nearly the same amount of power than a physical attack with all the amps from Kaido.
Luffy tanked one just fine.
Also, "Oden shrugged it off"? STOP WATCHING THE ANIME VERSION OF THE FIGHT. In the manga, the Boro Breath knocks him down, makes him bleed, then the manga goes out of its way to inform us, verbatim, that it was due to his endurance that he kept going.
Look at this terrible Dragon Ball tier logic,
"He didn't immediately die from a Boro Breath, therefore his ATTACK POWER scales to it"??????
What the hell.
Sorry Fluffy, you're outmatched.
