I know the few times I have tightened a Brooks, a quarter turn was enough to notice, and just a bit more started to raise the center ridge. And it’s not clear to me that Brooks leather is elastic enough to spring back after being stretched, unlike Selle Anatomica. I would only tension it less than about 1/2 wrench flat (1/12 turn) at a time turn at a time, or ½ stroke with the little Brooks wrench.
