Mitsurugi, i think you just proved my point with the resemblence towards tsunade and sakura.

Tsunade/sakura looked down on Jiraiya/Naruto. (Sorry about the misprint, early in their lives Oro/tsunade look down on Jir, but later it seems when they're older Jir/Oro look down on Tsunade.)

They never stated when exactly she had the freakish strength, but Tsunade/Sakura is smarter than Jiraiya/Naruto.

Now the details on physical strength dont apply but sakura does a have the strongest chakra control, which may be her best ability throughout.

Shes not good. We all know that, but we know they arent going to just kill her, so the only thing they could do is eventually teach her a technique
