Aftertouch Question

[A440A@AOL.COM]

Greetings, 
   Newton writes, and I agree with
<< You key dip of .450" is a bit deep.  Start with a dip of
.390" (10 mm) and change it -.010" or +.020". 

Then Newton writes, and I must question:

>>Deeper dip can produce a bit more power but the
price for that gain is too high except for strong
performance level pianists.
 >>

   IF the deeper dip allows a longer hammer blow to be had , then yes.  
However, if the hammer blow is not changed, but the dip merely deepened,  I 
fail to see how there could be more power available.  

Wondering,
