[X] Training Akane: Shadow Clone
If we assume Akane focused on SC this whole time, we could figure out the date Akane hit 1h clones and use that to help estimate how much her clones are helping Kagome decode.
I made a post about this, and it was referenced in the latest update - even assuming shadow clone, as long as Akane isn't spending over 12h per day on the notes, 40% decrypted is pretty good.
Still a good idea though
