Did you miss the part where the reason why it has None in every stat is because it's outright impossible to compare its abilities with that of existing Stands? It's not even singular, Japanese isn't exactly a straightforward language. It's context based.
And even if it was singular, it changes absolutely nothing, why's that? Because if it was possible to compare it still use the measuring rods, it would, which it can't, because
none of them fit it, because it's impossible to use them to quantify its abilities in any category.
And it sure as **** ain't like Stands don't get new stats upon evolving given every single Stand that has ever done that got it, whether that be BTD, Echoes Act 1, 2 , 3, Chariot Requiem, Whitesnake, C-Moon, Made in Heaven, Heavy Weather, Star Platinum: The World, Tusk Act 1, 2, 3, 4, etc all got new stats, and they all used the same scale, because even though in some cases they're hilariously superior, to the point it's not even funny (see Act 4), they can still be quantified using the scaling system.
Point is, Requiem's abilities simply can't be measured using the Stand stat system, it's impossible, it explicitly says that. And goes on record one page over even pointing out how
his attack power exceeds all existing stands in general (so yeah, he's not
just superior to GE in stats, he's outright pointed out to exceed
every Stand in attack, to give you an example of just how encompassing his superiority is), confirming that yeah, GER is hot shit.
