Hey guys, I think I may have found a solution to the Perospero problem.
So remember how Jack said that the near-death Scabbards are far above the Zoan Tobiroppo?
That would include the injured Neko, who would thus be above the Zoan Tobiroppo even while injured and in base, aka 477.6 gigatons.
Thus, since Perospero overpowered and tanked hits from Injured Base Neko (and was only overpowered by Sulong Injured Neko), Perospero would scale above him and thus also scale above the Zoan Tobiroppo, so he would also scale above 477.6 gigatons (aka, A-4).
Since IIRC Sulong Carrot and Wanda slashed his face via a double combined attack, they'd each scale to half of his durability/AP, so 238.8 gigatons for each of their Sulong forms.
