Exactly. One of the most meaningless statements in the RM. Note that this 
statement goes on to give a description of what it means: "...returning a 
wide spread of values for different string values. It should be unlikely for 
similar strings to return the same value." That's the important part; "good" 
really doesn't add anything here.
