If you turn to STBD to obtain heading, is the deviation 1.5 degree?
If you turn to PORT to obtain heading, is the deviation -1.5 degree?
There will almost always be some deviation between Plotted Course and Actual Course.
To obtain better accuracy use actual rudder control and Bearing Overlay.
To check Bearing Overlay Accuracy. Set Torpedo Dials to Zero (0) and look where Topedo Solution line is.
Also, some Bearing Overlay's have a built in deviation either on purpose or by accident.
The overlay is normally a 1024x1024 texture and line width is normally 1-3 pixels. This can result in approximately 1 degree deviation.
Line width should be 2 pixels so 1 pixel width of line is on each side of center line mark, or Texture size can be adjusted to 1025x1025 before creating bearing overlay.
