Figure 1 shows input flows between sectors that exceed 6%. Notice, there are no feedbacks.

Figure 2 shows input flows between sectors that exceed 5%. Now there is feedback between Utilities and Mining. Also, there is circular connection between Mining, Petroleum & Coal and Utilities.

Figure 3 shows input flows between sectors that exceed 4%. There are not new feedback. There is feedback between Utilities and Mining. Also, there is circular connection between Mining, Petroleum & Coal and Utilities.

Figure 4 shows input flows between sectors that exceed 3%. Now there is a feedback between Chemical and Plastic & Rubber Prod

Figure 5 shows input flows between sectors that exceed 2%. Several new feedback cases.
