almost equally unacceptable, while as power increases above 122
hp each additional horsepower really makes a difference. Suppose
you again use the mid-level splitting technique and find that your
mid-preference level for the range from 109 to 130 is 122 hp. We
want to modify the lower SUF range to reflect this. Make the
modification as follows:
1. Select the 109-130 range by clicking on its line. You can
also use the left arrow key to move the selection from
the split point to the adjacent sub-range.
2. Set the mid-preference level by typing the number "122"
in the "Level" edit box.
This results in the SUF shown in Figure 4-6.
Figure 4-6. Result of setting mid-preference level of 122 for range from
109 to 130 hp.
Similarly, you can set the mid-preference level for the higher
range. Assume that the mid-level splitting technique tells you that
your mid-preference level is 140 for the range from 130 to 175 hp.
You might get this result if you feel that there are decreasing
returns for horsepowers over 130.
