Because things are happening faster.  You use less time to accomplish 
the same mechanical work (hammer to string contact efficiency asside, as 
its a seperate issue)

You put 40 grams of force from the finger into the string... and you get 
more raw velocity out of an action with less friction then another with 
more. Lets use your draconian example... 20 swings on the one hand vs 3 
on the other.

It should be clear that for any given output velocity/force...etc... you 
will have to put in more effort in the latter then the former. The flip 
side of that is that you have less time in the former to do whatever you 
are attempting to do.  The window between max output and min has been 
made smaller.  On the one hand your fingers are required to be a bit 
stronger... on the other they are required to be able to exert greater 
sensitivty to control the increased response.

Its kinda like hitting a baseball....  a slow pitch is easy to get your 
bat on... but a fast ball... On the other hand.... once you get your bat 
on the ball it will generally fly farther..... which direction it flys 
is another matter entirely.
