You're not far off there. Mid diff at least for Big Mom to defeat King. But the thing is that's why it makes GB intro so insane. The fact that you can't believe he did that, and have to come up with all of this just backs how insane of a feat it is.
But we never saw what happened
I can make assumptions King was in fighting shape but it would be just that..an assumption.
Its much more demonstrative when Oda shows people neg diffing YC1 level characters
So far only Zoro and Kaido have been able to do that.
Tho King of hell Zoro vs King was a lot more ONE SIDES than Luffy vs Kaido round 1
