You are still assuming that I have something against sakura or tsunade, how can one grasp the strengths and limitations of a technique without looking at those that use it? By taking out sakura and tsunade you have sought to apply a no limit to the technique by using data book hype that has not been proven, I could just go on and say kaguya could destroy a universe since her TSB was said to obliterate the world and a world is vague concept it could mean a planet or even a universe. So I could choose which one I want to believe and state it is correct but those that match what is known, what is within the capabilities of the character that uses them? No.
Feats of characters will always take precedence over statements in the manga, over DB and then over fan opinions. Sakura has mastered the teachings, fact. Was she baffled? Yes. Does this suggest from what we have seen that her technique could not replicate it? Perhaps.
