sure if you know how lifting and hitting connection worked.But your only proof was a scene from a filler ^
Sakura >> Tsunade in hitting
Tsunade >> Sakura in lifting
This should be obvious even for you.
Sakura not lifting = she can't lift? Rofl what?
Sakura > Tsunade in strength, not just "punches "
My proof is the anime "filler" is a fan-made excuse when you can't use anything from the anime like me to justify your point, nor can you use anything from the manga. Since manga is canon, shouldn't be able to use canon to prove this "Filler" wrong? Oh wait you can't. Furthermore, that "filler" was towards Exaar, not you.
Both of their strengths have been credited to be the same.
Fans = Tsunade has magical natural strength, but we just can't prove it, we just need something to make her special from Sakura.
