maximum dimming percentage

there are at least three ways to do that: Proportion, Curve and scaled Park
Proportion means that every intensity in a cue is multiplied with this factor before being output. values from 1 to 200%.
Curve: you create a new curve where you type 100 @ 50 and then in patch apply this curve to the channel in question
scaled park: in the park display you type Chan 1 @ / 50 Enter. this will half the output value

1 and 2 will automatically be in place when you load that showfile, but not 3.
all 3 will NOT show the reduction in the Live or Blind display. you can see it in the output column of About
