I just want to mention some quick revisions that don't really warrant an entire CRT and can probably be settled right here as they are fairly straight forward and not controversial
1. Atlas Flame and Motherglare should upscale to 7-B+, they are shown to be far above Laxus, who scales to 43.9 Megatons, meaning they only need to be 1.2x stronger than him to reach the halfway point of 7-B, which is 53.15 Megatons
2. Hellfire Natsu should also scale to 7-B+, because he ate Atlas Flames Power and added to his own, that would mean he scales to 78.95 Megatons
3. Etherious Form Mard Geer should be at least 2x stronger than his Base Form, not because of a stated multiplier, but because he took no damage from the combined attack of both Devil Slayer Gray and Empowered Natsu, who were both at this point comparable to or stronger than Base Mard Geer, not to mention that he took no damage from Devil Slayer Gray who had the benefit of Devil Slayer Magic, which would have negged a lot of Mard's durability, and yet still, Mard took no damage, this would mean Etherious Form Mard Geer would scale to at least 449.8 Megatons
4. X791 Dragon Force Natsu completely overpowers and wrecks Etherious Form Mard Geer for the entire time he is in the form, Natsu only needs to be 1.2x stronger than him to reach the halfway point of 7-A, which is 550 Megatons, so he should scale to that
This all pretty straight forward and affects very few characters
