Honestly, Skylar, which way would you prefer? You are the resident expert on this topic.

I'd say he'd be able to tell there is SOMETHING majorly different about how Hana compiled her part of the ledger. While the cover summary page of the Mitsumine holdings and Tenzen's writing are what he's used to, Hana's sections are a mix of single and double-entry accounting which she purposefully slipped in to gauge how her lord would react. But the fact he's paying attention to what is written in the first place has Hana coming to like the guy.

At first glance, he'd think the double-entry accounting is just a brand new cipher she made up. But its enough to arouse some curiosity in why Tenzen sent her when she is so able in numbers by conventional standards. Perhaps enough to warrant keeping the lady around to wrangle some answers out of later as to what she's really writing.
