@Ninja of War You're assuming Shisui himself can only use Koto every 10 years per eye. That is an assumption alone that literally makes no sense. The crow on the other hand?? Yes it does indeed need 10 years to recharge. Example is Itachi put the eye in the crow when he was 11 and and Shisui died, before that Shisui said he attempted and failed to use Koto(on who Idk) so skip to 10 years later and its the year Itachi dies from his sickness, but the time of the 4th War. Itachi's summoning crow still has the eye and can finally use it, as 10 years has passed by. Shisui himself was never given some time limit on the move, you made that up.

Edit

Uchiha massacre took place 2 years AFTER Itachi obtained Shisui's eye and put it in his summoning crow btw, wanted to correct my other comment.
