Things to try
- Set the convergence angle to its smallest value. Compare the bars again.
- Move the bars closer together with the bar gap slider. Note what happens to the difference you see.
- Make the bars longer, then shorter. See whether the pull changes.
At the default settings this image measures 700 by 480 px. The sweep on the Ponzo page tracks Angle between the rails (degrees) and marks these values as weak: 5 to 15 deg.
