but you are applying double-standards in your reasoning there.
if you demand scans to accept the simple conclusion that Surfer's speed (which is instantaneous) is applicable in battles too, then you should provide scans for your hypothesis that Superman has Surfer level durability.
I mean, off the top of my head, I can tell you that Surfer must be more durable to be able to negate the affects of ALL cosmic radiation upon his person, which Superman cannot do, he cannot endure Kryptonite nor Red Sun radiation... that is a durability issue is it not?
also Surfer's durability is far more than sufficient to cope with anything Superman has to offer in terms of offense. consider the kind of punishment Surfer has taken from beings far and away more powerful than Superman. Galactus has blasted Surfer, T&A have gone to work on him big time and of course there's UniLord a dimensional God who couldn't kill him.
I don't see how you can possibly argue that Superman's fists now somehow create enough force to do what T&A could not 😐.
