That is the only way I can think of him knowing how many times he could use his ultimate genjutsu. How do you know how many times Shisui could use Kotoamatsukami? The crow and Danzō don't really count since they weren't the original wielder.

Its stated shisui can use kota once a day per eye.(Total of 2 per day)

@Lion Chakra You dont know when shisui unlocked MS, it was never revealed.
