   I can give you two data points on the subject. The most complex application   
   that I know of using Fuzz-C had a total of 70,000 rules. (I am sure they were   
   not all needed) In the Lord of the Rings film Fuzzy logic was used to control   
   the behavior of each of   
   the animated warriors, I believe that for each warrior type there was rules in   
   the low hundreds executed 10's of thousands of times for the whole field of   
   battle for each frame.
