When working with git master branch, or 3.22.2, QGIS Azimuth and Distance plugin seems to add a constant offset to the azimuths entered. I am working with CRS EPSG:22717 NAD83(CSRS) epoch 2010 for both project and point layer. I add to Active layer, using Survey type Boundary, Angle type azimuth or bearing, Distance unit Default, Angle unit Degree, North type Default. I choose a point on the map, and create a segment 100m Azimuth 0, then Draw. If i use the measure bearing tool, i get around 0.32 degrees, and it seems to vary slightly each time i draw from a different starting point, but if I delete the drawn, point and snap to the same starting point, i get the same offset.

I now understand this is due to meridian convergence. I will work on a pull request to add the ability to enter the convergence angle to each bearing.
