Yes, and that's the feat I took for his best traveling feat. If I must, I'll include his the end of galaxy statement as the baseline, because of this:
They said he "finally reached" meaning the baseline of ultima cosmo is him reaching the edge of the milky way, that is completely true. However the speed I'm using for to upscale god tiers comes from his edge of universe statement where they stated "has reached" meaning it could be in the future relative to the galaxy one. So baseline for cosmo will be the galaxy one while every god tiers will scale to his edge of the universe one, are you fine with this?
Sometimes the "translation" is not really "translating" at all, they might write extra stuff more than just translating (like look at
Gravi's page where they stated that he traversed the universe and gather cosmic power and whatnot in EN instead of whatever the JP ver wrote for example), so unless a potential error in translating Kanji is present (like Lumina's EN), I don't think it will contradict anything, of course it depends hugely on the context like the Cosmo one, sure.
I might need clear clarification for this one on the explanation page, that is if you're fine with what I'm proposing.
