The feeling of the tail hitting the backcheck will be missing from the key, 
and repetition power will suffer because under fast repetition there is 
virtually no blow distance.  Very few pianists can play extremely rapdily at ppp 
level! 
   Repetition depends on how fast the key returns and how far it has to go. 
It is instructive to compare the key return speed between two adjacent white 
keys.  Play one firmly enough to go into check, and slowly lift the other so 
that it doesn't.  Release both keys at the same time and observe that the checked 
key will come up much faster.  However, the unchecked key has much less 
distance to travel before the jack is reset. 
       If the hammer doesn't check, but rather, stays up at the drop level, 
you may have fast repetition but little power.
