It gives you direct information as to the firmness of the bushings 
relative to the weight they must support.  And it tells you that the 
friction for that weight is such that it provides a resistance that 
yeilds a consistant acceleratation.  Which is why I prefer that over 
Steinways  even friction priority method.
