   Sounds reasonable (or even quite good) for such a cheap sensor. Does yours   
   come with a datasheet that specifies accuracy limits?   
      
   The datasheet on the Sparkfun website claims "the ranging accuracy can reach   
   to 3mm", but does not give any guaranteed limits - and I believe there are   
   lots of clone parts thay may be even worse.
