Big, subtle differences that may be too complex to ever fully 
understand. For example, farmers and pesticide applicators know there
are big predictable differences in the effectiveness of different
insecticides even if they are both be applied to the same field at the same
rate. One might give a 25% kill. Another 75%. Yet both give a 
100% kill in the laboratory.
