I suppose you mean that the damper returns too fast down on the string? 
if so, that is a purely mechanical and controllable situation.

btw...... I got the impression that some people think that I meant the 
hammer to check high on the back check.

That is not da case.

I talked about adjusting the height of the back check and checking the 
distance between the hammer tail and the top of the back check AFTER 
drop, which then should be 2 mm. In fact the hammer has not checked 
because we slowly depress the key so that let off and drop take place 
without the hammer actually bouncing from string into back check.
It remains a mystery to me.
What also remains a mystery is why a tone improves after installing 
brand new back checks.
We often replace worn back checks completely because it is faster and 
more economical, instead of replacing the leather.
Every time we replace the complete back checks the tone is 'newer'.
