@othus12: Not really. You see there was a calc like that very early in the series given the Quick Sword an absurd mach speed so it was thrown out. Later then many feats appeared which supported that which is why it was accepted. You have Riful getting away from Galatea's giant sensing radius in just a second. Alicia and Beth crossing a great part of the island to fight Riful. Miria and crossing great distance while fighting with Hysteria even though they were not moving with a goal but just back and forth and clashing, Clare and the others dodging Destroyer spines (the others did it with Clare's help tho) and ofc Priscilla blitzing Riful over an absurd distance and lastly the first Quick Sword calc which made sense after those feats appeared. All those are very consistent and support each other. And you see in this case they are feats, go distance/time and you get the exact speed, it's something that can be observed, on the other hand OP only has a very inconsistent and out of proportion statement which contradicts the rest of the series and as such can't be accepted till feats don't show up which support any of that.
