That's a question you'd only ask if you thought you might know something different. ( shikamaru takes the book offered, hands coming free of his pockets. ciphers don't usually give him that much trouble. not like he'd completed any at the academy, but that had been due to sheer laziness. these days he doesn't usually downplay his intelligence from his companions.

he skims certain sections quicker than others, taking his time on the chakra information. it more or less matches what he's noticed himself, and knowing how much they're out is helpful. a medical perspective is more precise than his own as well... )

I can give you data on my own chakra fluctuations to supplement this. ( he hasn't forgotten her question. he's just considering how to answer it, or rather...analyzing sakura herself. )
