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.

I thought he can only use the power once every 10years. I did not know he could use it twice a day. I made assumption on age based on this logic.

The crow can use it every 10 years due to unknown reasons, most likely because its a crow, not a uchiha or a human for that matter.
