This question pertains to the U.S. version:
A window marker's position is defined in the Marker Settings panel: "Marker Position" and Marker Offset". Default shows a value of 20 for "Marker Position". The same units are displayed in the Tracker when editing.
I can't tie the units to anything I recognize. What am I missing?
