Yes, only I can't say I ever did it counting beats. It's 
proportional, and the greater the pitch change, the smaller the 
proportion, I think. In other words, a smaller pitch raise gets a 
greater overpull percentage than a larger pitch raise. I never 
actually measured it.

Similar.

Unless it's a Kimball, then nothing you try will work anywhere 
nearly the same as it did on the last one. <G>

There certainly are, because you can't help the strings render 
through the bridge by pounding. The back scale has to pull it 
through all by itself, in it's own time.
