I can't find the calc atm. I think it may have gotten lost when the site changed happened or I'm just bad at finding it idk.
I can show the feat in question tho for you.
Maybe the calc itself is still around and someone else can link it.
No problem, thanks for posting the feat.
But from the pic and feat I failed to see how this is a island level feat. Yeah shockwave seemed to be the size of the stadium and was impressive but nothing the size of a mountain or an island.
And Shiryu managed to block it with bare hands without that much trouble and managed to kick it to the air just after. And Shiryu while strong is not at the top S class level. SO if Shiryu could push back island level attack without that much trouble it would be a bit too much from him story wise portrayal wise etc.
Also given the story of this arc I think Choze while strong (recognized by Gouketsu) is not THAT strong.
First Shiryu beat him like mid/high diff, stopped his blast bare handed etc.
Then he got mega stomped by a real Dragon level monster : Gouketsu.
And after that Bakuzan appeared to be dragon level too (a lower one). His entrance and introduction led us to think he was stronger than Choze.
So I don't really buy the island level feat.
