I don't know, somewhere around 180, I've stopped grinding bp a few months ago when selling bp became less profitable.
To the guy saying that quick claw isn't reliable, you're right it isn't. But on a poke as slow as slowbro, it allows you to get a kill without taking damage every once in a while. It is far better than any berry you could put on it. (Assuming lefties are taken by Blissey here).
