12 years old Konohamaru was better than 12 years old Naruto imo.

But yeah, Sage mode + Kurama are not power ups that Konohamaru has access too (well, maybe he actually has sage mode, who knows?) so this is no surprise his progression curve is not as impression as Naruto; But even then, there is no way his progression is THAT low.
