Ok, here I am.
First, let my say I heavily disagree with everything proposed here.
For starters, assuming Ryu tanked anything in the first place is rather preposterous. The 7-A rating is the force needed to v.frag the island, which was delivered by Akuma's punch, which hit the ground and not Ryu. Second, as Rusty said, you have to account inverse square law, and even then you should start from the actual explosion, not the punch that triggered it, as they are separate events with different magnitudes.
But what matters most, is that the island never exploded, it crumbled apart. Not only we never see what happens to the island itself, as it could have been destroyed in several different ways, but most importantly, we have solid proof it didn't explode.
The
english translation says twice that the island disappeared (first from Ryu's own words, then from the narrator's), but the
original text goes as follows:
「うわぁっ!? し、 島が崩れる・・・・!?」
・・・・ゴウキの島 『獄炎島』 は崩れ去った
"Whoa! Sh, the island's collapsing ・・・・!"
・・・・ Gouki's island "Hellfire Island" collapsed.
There's no way to quantify what amount of damage Ryu could have sustained, if he ever sustained any, as if he's shown completely unharmed and hurting him wasn't even Akuma's purpose.
I could go on and write a quite long and exaustive essay on how using the other feats presented don't really work as support, how characters on Ryu's level are solidly portrayed as a step above the others when going down in the tier list, how there are dozens of instances and statements of characters either weaker, equal or even stronger than Ryu being threatened, wounded or straight up killed by stuff that isn't even close to tier 7, or the simple fact there are no solid feats on that level.
I can also say this is all stuff that was presented, debated and accepted in the past, over the course of many CRTs.
But I believe that proving how this feat doesn't count for durability and didn't happen in the first place is enough.
