The Scroll of Sealing Shows one HOW to use a technique, its not just a basic account of its usage in a battle. So I don't think the logs would explain how individuals used their techniques just what they called them and what they did.

And as such, while I am not an admin so my opinion is purely for the sake of preserving the canon, it would be impossible for Sayuri to gain abilities from such logs as no one would know exactly how enemy techniques (ie: Tengai Shinsei) would have been possible. As Madara didn't tell anyone and majority of the war had not faced a Rinnegan user (as only Pein attacked the Leaf) so they wouldn't attribute it to the Six Paths Technique as they wouldn't know about it. On the flip side none of the leaf shinobi would be able to prove that Madara was using path power to pull down the meteors. Ijs. So using the "logs" defense as how she learned jutsu exclusive to particular Shinobi is not valid.
