[@Kal-El]I thought that was a thing. . . but you have to admit, even with a month of training, it's annoyingly bullshit to have another character's hard work be instantly undercut like that, even if Sasuke's a prodigy and he can't keep it up for that long. Or maybe it's just annoying. 

Whatever the case, I think this is just one of those cases where we'll just have to agree to disagree.
