Danzo used was able to use it twice in one day, the second time he was going to use it he was stopped by Sasuke stabbing right through Karin. Remember he was going to use it on "Madara" afterwards. Now with Hashi cells he could use it twice a day but he was not an Uchiha or the eyes original owner. So with Shisui I would say its more likely he could use the tech once per eye once a day going by how Danzo could do it. The Crow on the other hand is just that.. a crow. It can only use Koto once a decade.
