There's a massive difference in time between "1 hour" and "10 years". An hour was with Hashi bodyhack cells, and 10 years was in a crow. I think it's safe to say it's somewhere inbetween. Even then, an hour inbetween each use isn't even spamming. Rasengan, that's a Jutsu spam for ya.

As to it being the most overpowered technique ever? yes definitely.
