Matrix diagram of two-stage efficiency. Notes. ① The value of a dividing point on the vertical axis = the average efficiency of the second stage; the value of a dividing point on the horizontal axis = the average efficiency of the first stage. ② The average efficiency of each stage is shown in Table 2.
