Parellel Segments: Longer or Shorter?

Is it easier to match the slope of a shorter segment or a longer segment?

Drag point P to match the slope of the shorter segment. Drag point Q to match the slope of the longer segment. The "score" is the difference in the angle of elevation between the target segment and the segment you are moving. Enter your data in the google form at the bottom of the page.
