Have you ever read the wiki page on how stat boosts from improvements are applied?

Even though Kongou's shot doing more than Nagato probably isn't very relevant to the AP shell, a +7 T91 will have +2 firepower, while +1 T1 will have +1 firepower, so they'd be about equal, though pre-cap modifiers might tweak the difference by a point.

Anyway +10 T1 would just be too horribly expensive to practically achieve, since it eats ton of AP shells and would only have about 1 point of each firepower and accuracy over a maxed T91.
