How do I scale the map and icon to be at the optimal zoom factor?

In making an overview screenshot the scale was 2.09, twice what it should be.

1.3 is considered to be the optimal zoom factor.

At 2X scale: In game play, the minimap HUD display shows the icon as too big.

Change the text file to 1X: The icon is perfect size but the minimap is now too small.
