According to the man page the 2nd parameter is the threshold at which 
the acceleration value is applied so I'm not surprised that you don't 
see any difference between 0 and 1.  Even 4 might be hard to see.  I 
think that to see a difference for fine motor this value will have be in 
the 5 to 10 range.
