1 - It'd just be part of the Character's Scaling Chain. See #2
2 - If all of the Characters involved in that Feat are
7-A, then it'll just be part of the Character's Scaling Chain for their Justification
In example, Linley (
7-A) one shotting other Characters who scale to him (
7-A).
On a VS Thread, he'd be unquantifiably stronger than baseline
7-A, so if anyone wants to find out how strong Linley is, then the answer that could be given is "He is unquantifiably above 50 Characters who are 7-A's by one shotting them all in a single blow"
I could've sworn that there are plenty of Feats that are above
7-A in Coiling Dragon though
The OBD has some Calculated

And I'm sure there are more, with some dude creating an Island or Continent or some shit on the MC's Planet, which I think is Bluefire, or I'm misremembering things -

I forgot most of the Feats though, so I guess these guys' statements can be used

"also supported by the fact that Jenkins (A total scrub) can travel hundreds of thousands of kilometers in less than twelve hours...under gravity hundreds of times greater than that of Earth." - https://www.narutoforums.org/threads/linley-from-coiling-dragon-ring-vs-3rd-raikage.1037536/page-2
"Sovereigns can destroy entire planes with their aura, which is star level, and Linley can resist that aura with his Will. Linley is star level, and sub-relativistic at the very least. He one-shots." -
