Figure 4.
The line graph plots month on the horizontal axis from 1 to 12 and value on the vertical axis from 0 to 3.5 million N Z D at intervals of 0.5 million. C C rises from about 0.3 million N Z D in month 1 to 1.2 in month 2, 1.6 in month 3, 2.0 in month 4, 2.2 in month 5, 2.4 in month 6, 2.5 in month 7, 2.6 in month 8, 2.7 in month 9, about 2.8 in month 10, 2.9 in month 11, and 3.0 in month 12. E X C 1 starts near 0.2 million N Z D, rises to about 1.1 in month 2, 1.5 in month 3, 2.1 in month 4, and about 2.4 in month 5. It then remains close to C C through month 7, reaches about 2.6 in month 8, about 2.7 in month 9, about 2.8 in month 10, about 2.9 in month 11, and just under 3.0 in month 12. E X C 2 starts near 0.15 million N Z D, rises to about 1.0 in month 2, 1.5 in month 3, 1.9 in month 4, and about 2.4 in month 5. It then follows closely with values around 2.4 in month 6, 2.5 in month 7, 2.6 in month 8, 2.8 in month 9, about 2.8 in month 10, and 2.9 in month 11.The model behaviour verification
